Substitute & Interchangeable Parts

Owning a Triumph can be costly when it comes to purchasing parts. And some parts are not made will while others are no longer available. That is why we built this page. It lists the non-Triumph parts found by clever owners that will work just as well, if not better.

Most, if not all entries on this page, were sent by Spitfire & GT6 magazine readers. We try to double check that the information is correct or as clear as possible but are not always able.

This page will stay in a constant state of construction. If you have any info that you would like to add to this page, please email us.

carbon canister1971 Oldsmobile Firenzacarbon canister, three hose version, made by Coopers in the UK – identical to a late Spit
carbs (Zenith Stromberg)SU’s from MGB or Mini72-74 MGB’s used a SU HIF4 carb (1 1/2″). They have four mounting holes. You can also use a HS2 from a Mini from the early 70’s. They have diagonal mounting holes that will line up with the holes on the single Zenith intake manifold.
I read about this conversion somewhere. Anyone done it? Let me know how it went.Update: the MG was either a twin HS4 (1.5″) or HS6 (1.75″) carbs. HS4 carbs have 2 diagonal holes, HS6 and larger have 4 as far as I know – And all HiFs have 4. The HS2 as found on Minis and many other small BMC/ BL cars is a 1.25″ carb. It is also easily identified by the mounting holes being vertical, not diagonal!NEW!  Here is a link to more info.

choke cableuniversal choke cableIf you want to convert from auto to manual choke (which I recommend), and don’t want to pay $80 for one I suggest going to your auto parts store (Autozone in my case), and in the “HELP!” section they should have a few different types of cable. One of them even has everything you would need to convert for about 15-$20, I got the cable by itself for $6 and fabricated my own linkage and brackets. Just remove the auto choke housing and from there you can see how it works and what u need to make it work. Its simple to do and much more functional than the automatic choke.
con-rod boltsFord Sierra Cosworthvery strong bolts for racing, $34 a set, these bolt straight in! As used by top Spitfire UK racer Jon Wolfe, use standard torque when tightening these up.
distributor75 and up MGB and MidgetLucas 45D or 45D4 distributor is a straight swap, fits 75 and up (earlier ?). 25D will also fit.
EGR blanking plug1930 Model A Ford oil drain plugWhen you remove the egr valve you need a plug that is not easily found. On the Ford the oil drain plug is a perfect fit. Size is 3/4 x 24 fine thread.

Nissan 1400 LDV
(New Zealand)
This is a straight fit. Only mod is to fit spade connectors to the wiring harness. Ignition includes switch.
electronic ignition
(late 1500’s)
Rover Metro/Maestro’sthe electronic system from certain Metro/Maestro can be fitted very cheaply as it can be obtained from scrapyards, the contactless system can be fitted directly to the existing distributor so the correct centrifugal/vacuum advance is used. In actual fact you should be having little trouble with the existing points setup.

standard 4-pin GM Ignition Module
part number TP45SB for 1980 Chev. Chevette w/1.6 L engine.
Take the box off the firewall, pull the screws off of the back of the box, pop the panel off, and there it is, a GM 4-pin ignition module (along with a capacitor and a zener diode…). Switch the wires from the old one to the new one (straight swap, spade connections), apply the conductive goo (usually included) to the back of the new module, and carefully secure the new module. Further note, watch all the grounds ( be aware that the GM module body grounds to the Lucas box which grounds to the car body).

1980 Chevrolet Camaro 229 V-6 with HEI 4 wire moduleThe original 1975 to 1980 CEI ignition amplifier contained internally a GM ignition module used in the 1980 Chevrolet Camaro with a 229 V-6. This module is a standard HEI 4 wire ignition module and is readily available at most stores.
engine (1500)MG Midget Mk IVThe engines are identical, despite the fact that the MG version had an entirely different set of part numbers to the Triumph version – it must have taken a genius to decide on that policy.
engine (GT6)TR6 engine blockGT6 & TR6 used the same block but had different heads and crank/rods/pistons. A piston/con rod/crank swap will add 500cc’s!
fuel pump block off plateBig Block ChevyThe plate is a bit longer, but the studs match and it seals completely
fuel tank float94 Ford Ranger (and probably all in that year style’s rangeI work at a mechanic’s shop, and as we were replacing the fuel tank on my 74 Spitfire 1500, we noticed that the float was bad. Our lead mechanic exclaimed, “Hey, I just replaced that in my Ford Ranger two days ago.” Straight swap, and obviously cheap.
head (1300cc)Triumph Toledoa late Toledo head (218141 – 8.5 with 1296cc) or a late Mk IV head (218142). These heads have the biggest standard inlet valves, and will increase BHP at the top end

head (GT6) TR6 headI put a TR6 head onto my GT6 block.  Straight-up match.  The only hitch, you have to use the TR6 manifold gasket.

Purolator L10017
oil filter (cars with spin on filters)Ford V8 filter
(Fram TG3600)
“I have always (for the last 25 years) used the Ford V-8 filter, with an adapter. (old # PF-1, etc.)
It’s a large filter, with lot’s of surface area for cooling the oil, and holds a full quart of oil, extra capacity without a custom oil pan. For those with clearance problems (the Ford filter sticks out a bit), use a Purolator L10017. It’s like a shorter bodied version of the Ford filter, same base, threads, etc. It’s good if you use a sandwich type oil cooler adapter.”
oil pressure switch (1296cc)Chevyan oil pressure switch from a 1970 Chevy 250 cubic inch 6 cyl motor for $2.99 will work on a 1296 cc motor.
oil pressure switch (1500cc)GMNAPA’s Echlin #OP6610 is a direct replacement for the three connector switch for 1500’s with the anti-run-on valve
oil pressure switch (1500cc)Chevrolet Monza

Oil Pressure Switch part #PS-64.  It is made by Standard Motor Products Inc.
pistons (competition 1200cc)Cooper S pistonsreboring to 70.6 mm, you can fit Mahle flat top forged Cooper S pistons (GR2) Shorten the skirt.
pistons (1300cc)Ford Fiesta pistonsEngine capacity can be increased to 1350cc by boring out to + 60 (Ford Fiesta pistons can be used but anything bigger than +60 can lead to head gasket problems) and this will increase the torque. If high-compression pistons are used, lower compression head will need to be fitted otherwise excessive pinking

valve cover (GT6)TR6 valve coverTR6 and GT6 valve covers are interchangeable
Straight bolt up, except that most aftermarket ones lack the groove to hold the gasket, as well as some emissions hoses need to be changed since aftermarket covers’ blow-by hose comes out in the middle, rather than towards the front.

heater fan motor (interior)’84 Chrysler K-car rad fan motorThese motors are virtually identical, but you have to drill out your “hamster-wheel” to 5/16″ and re-use the original mounting flange. Also must run through a relay and switch (1 speed only and you’ll catch your original switch on fire if you use it)
heater temp control cablebicycle brake cablesless than $3 from a bike shop, and are less prone to crimping than aftermarket choke cables

The bonnet release cable on Mk2’s is very good quality, self-lube solid core and makes an excellent heater control wire replacement.
radiator1986 Pontiac FieroThis requires a little modifications. First you need to cut the old brackets off flush with the frame. Bend these old brackets around the bottom edge of the Fireo radiator and squeeze them tight. These will now act as a reference point. You can either weld these old brackets to the frame, or you can bolt them in. I used the top of the radiator cover from the Fiero and used nylon tie straps to secure the radiator to the Spitfire frame. Now you have an Aluminum cored radiator which will help keep your overall temperature down. The alternator bracket can be lifted up to use as a support for the upper hose.
radiator (Spitfire only… clearance problems with GT6)Peugeot 205 radiatorAluminum cored, full width radiator. Can use whole assembly with expansion tank and fan and hoses and wiring. Fits in easily with some simple brackets once the standard radiator and ‘U’ frame are removed. A Vitesse thermostat housing which goes to the side and then back a little avoids the top hose fouling the alternator fan. I got a whole assembly from a scrapyard for £25.
radiatorRenault 12 or DaciaThis is a straight fit and fits in the U frame. It is a full size radiator. Dacia parts are sold everywere in Roeminia, new and very low priced!. But for most of us not a place were you come often. The Renault 12 is equal. The connection for the hoses is exactly the same as with the original. Changing to a Peugeot radiator is also possible but much harder because the hose connection is different!
radiator fanMaestro / MontegoFit the fan in front of the UK spec radiator connect up a simple switch. Mounting using rubber tube and bent steel brackets requires no modification to either fan no rad just clamps on
lower radiator hose1964 & 1965 Chevy ChevelleA 1964 Chevelle 194 and a 1965 Chevelle 194 engine w/o ac will fit the 1973 to 1974 Spitfire water pump to tee lower hose and will also fit 1976 to 1978 lower radiator hose.

Thermostat housing gasketFel-Pro 35568“35568” is an absolutely perfect match except for the mounting holes being off slightly. They should have made them oblong like most gaskets. But scissors or a sharp knife will do the trick.
Nice heavy pile to the gasket and it seems a lot more durable then the paper ones.
thermostat cover (1979 & 1980 Spit)1300 & 1500 front wheel drive TriumphsThe thermostat cover on the late US Spitfire was originally fitted to 1300 and 1500 front wheel drive Triumphs in the UK.
thermostat (GT6 MKIII)Any 54mm thermostatAny 54 mm thermostat will fit a GT6, not sure about other models, but its much cheaper and faster to get than a stock replacement.

(from 78-80 Ford Fiesta for example)
Many Bosch altenators are a straight swap for the lucas one. It is more reliable, widely available and cheap (second hand). The mounting and even the connector are the same. Sometimes you have to use the old fanblade (easy to change). Be carefull with very heavy types (high amp)
Minor changes need to be made to alternator’s pulley and fan blades

hornsRover 600 / Honda AccordI have fitted Rover 600ti horns to my Spitfire. They are made of hard black plastic so they won’t rust. The Rover mounting brackets can be used on the Spifire without modification.
ignition switch wiring plugs1971 Oldsmobile Firenzathe 5 pin socket ignition switch wiring plugs are identical to the Spit
starter (GT6, possibly all)Will not fit LHD Spitfires…steering column rubs1989 Isuzu Trooper II 2.6 liter
part # 17155 or 16878
The swap was a physical bolt on. The Isuzu costs $72.99 (Autozone) with a life time warranty. You do have to change some wiring to bypass the original Starter Solenoid Wiring. Moved the original “solenoid to starter wire” to the upper lug on the Lucas solenoid and extended the original white/red “Ignition switch to Solenoid” wire to the solenoid on the new starter. Basically, I am using the old solenoid as a junction block. GT6 photo 1989 Isuzu Trooper II 2.6 liter part number 17155 (best fit but may no longer be available) or 16878 (larger body than 17155)See this link for very detailed info.
starter (GT6, possibly all)pre 75 Volvo
(year?, model?)
Don’t remember what year (pre 75) starter we used but it bolted right in with no wiring changes. My local parts supplier has three buildings of British parts and other foreign parts so I think they just kept trying different starters till they found one that fit.
Let us know if someone has more info.
starter solenoid (all)Ford solenoid from Mustang or F100$6.50 as opposed to $25
clutch master cylinder cap2000 Chevy Cavalier capA really nice looking cap for your master clutch reservoir. A 2000 Chevy Cavalier fits perfect and it has specs written on it “use DOT 3 or better”. Fits my 1972 Spitfire. 
differential ring and pinionTR7 ring and pinion (3.63:1)TR7 4 Speed diff’s ring and pinion (3.63:1) has the same part number in the factory manual that the European Spitfire used. Essentially meaning that you would be able to attain a 3.63 ratio by using TR7 ring and pinion in the Spit’s housing
Spitfire differentialGT6 differentialDirect replacement for Spit diff – has 3.63:1 ratio as in TR-7 but easier than replacing ring & pinion. Revs 1,000 RPM lower for same highway speed. (Speedo shows 10 MPH lower for same rev’s)
GT6 or Spitfire differentialDatsun or Subaru R160 Limited-slip differentialvery difficult with much fabriating and welding
gearbox (GT6)Triumph Dolomitedirect bolt in, need to use the Dolomite clutch plate. Stronger transmission than original transmissions.
gearbox (GT6 and Spitfire)
gearbox (1500)MG Midget Mk IVGearboxs can be interchangeable (if the correct rear housing is fitted that will take both sorts of mountings), but the gearset is entirely different – being a modified Marina 1300 set. All the other gearbox parts are interchangeable ie hubs, synchro rings, bearings, forks. The same genius who decided on the engine part numbers was probably in charge at this point – take the mainshaft, the Triumph version has a hole in for a ball bearing to lock the thrust in place that fits under second gear, the MG version doesn’t – brilliant planning making virtually identical parts in different factories under two different part numbers and was probably part of the reason for British Leyland’s problems.
gearbox (Spitfires)overdrive gearboxStraight swap, however due to the added length of overdrive, you will also need the shorter drive shaft that originally came with the OD trans and new rear trans mounts
gearbox mountingIsuzu Trooper3.2duty, LWB, V6, 24 valve Petrol, K reg (1992)
Overdrive solenoidVolvo or Ford solenoidAll J type solenoids are interchangeable so Volvo and Ford ones will also work

Brakes, Suspension & Wheelspartreplacementnotes
anti-roll bar (pre 1973 Spitfires)anti- roll bar (73 and up)73-up cars have a larger front anti-roll bar (approximately 15/16 inch instead of 11/16 inch) which, while not as good as a one-inch aftermarket bar, is a cheap junkyard upgrade.
beauty rings (wheel trim rings)Dodge Omni or Plymouth Horizon (TC3)
Ford Escort & Mercury Tracer
Wheel trim rings (beauty rims) will fit Spitfire’s stock 13″ wheels perfectly. I bought 4 beautiful ones, $20 salvage yard. Its an alternative to Moss,Vic, TRF. etc.
brakes (GT6 front calipers)TR-6 front calipersTR6 calipers up to CC81078 (1972) are identical to GT6’s through mid 72
TR6 calipers from CC81079 are identical to GT6 calipers from mid 72 to 73
brakes (GT6/TR6 front calipers)1979-83 Toyota four wheel drive pickupWith some mods the Toyota calipers fit TR6’s. Since TR6 calipers fit GT6 then the Toyota ones should also fit. Visit link to VTR site for conversion.
brakes (Spitfire front calipers/suspension)GT-6’s stronger front discs, vertical link, calipers and hubsStraight swap but must use everything between the A-arms. Not sure if they will fit all years but probably safe to assume Mk1-2 GT6 fit Mk1-3 Spit and Mk3 GT6 fit Mk4-1500
brakes (Spit front calipers)70s Ford Escort (Euro)Front brake calipers fits, but the brake hose comes to different place, so you have to change the hose: (from Opel with “banjo type” fitting) to clear the suspension parts when turning the wheels.

Jensen Healey, Delorian, Porsche 911S & Carrara, Morgan +4 & 4/4According to this Morgan site the caliper piston 32320329 and rebuild kit SP2697 are also used on the following cars:
Jensen Healey; the rear of the Delorian; Spitfire (67-80); Porsche 911S (74-77), Carrara (72-75), 911SC (77-on), Morgan +4 and 4/4 (61-85). The calipers are different.

brake pads (MkIII-1500)Volvo 240 (rear)Stock Volvo pads from local Volvo dealer (fitment is REAR pads for 240’s with Girling rear brakes). Major improvement! Lighter pedal feel, much better bite! One thing, don’t use the black mastic anti-vibration pads that come with them, just use the aluminum shims. The mastic pads make the pedal feel squishy, and taking them out made no difference in the amount of brake noise – there is none either way. They were about $30 for the set.
brake pads (GT6)Datsun 240Z
brake light switchAustin MetroExactly the same part, so straight swap, no modifications needed. Cheap new and abundant in scrapyards.
brake light switch73 Chevy Nova switchGo to ANY Auto Parts store and ask for a 73 (non-cruise control) Chevy Nova switch. They make two, one that is metal and the other is plastic. Less than $10.00. It works great but you do need to shave off part of the threads, like it is on the OEM unit, so it will fit.

master cylinderDatsun 510The flare fittings are metric, so I had to cut the end of the brake lines, then re-flared them with metric fittings. The master cylinder used the same bolt pattern, so there was no problem bolting it in. The Datsun MC is designed to sit level in the car but have had no trouble with the Spit’s angle.
master cylinderToyota Tercel (US)had to modify mounting bracket and add metric fittings
master cylinderTR7Same size, angle etc. But the TR7 used a larger pipe and pipe fitting. The flare was cut off. A suitable ‘large’ fitting was substituted for ‘small’ pipe for $1.
shocks (rear)13.5 Harley-Davidson MotorcyclesRemove bushings from Harley shocks replace with 3/4 inch long pieces of heater hose. With 5/8 inch diameter. This will raise the rear of the car up by about 1.5 inches to get rid of the sag common on the spit. Did this on my 1977 1500 worked great cost $25 including shipping on ebay. Most Harely owners remove these as soon as the get dirty or to lower their bikes cheap and plentiful.The ones I purchased were for a 2004-05 XL model with 13.5 eyelet to eyelet measurement. Most motor cycle shocks that measurer 13.5 to 14.5 would work as long as they have eyelets on each end. This raised my rear end up by a little over 1.75 inches. The Harely have a little larger eyelet opening than most Asian cycles but they still could be used. I even installed a pair to lower my Yamaha 750 down by 3/4 of an inch last year (required a thin steel bushing do to hole size difference). The 77 Spitfire drives better and now sits almost level since installation.

springs (front, US 1500)Mk3 Springs (214144)Gave me back the phenomenal handling and stability Spitfires were world renowned for.
The 214144 early spring is rated at 150lbs rather than the later TKC1884 being rated at 180lbs. Visit Paul’s website for details.
springs (Spitfire front)springs (GT6 front)GT6 front springs with one coil cut off work well on a Spitfire
wheel bearingsSpitfireTR6 front wheel bearings are the same as Spitfire
wheel bearingsGT6GT6 front wheel bearings are the same as the Stag. Victoria British and Moss use their own part numbers so you can’t tell from those catalogs but if you look up the factory part numbers it shows they are the same. GT6 and Stag share the same front outer wheel bearings as the MGB, MGC and MGBGT.
wheelssee the wheels page for more info about other brands/cars that fit Spitfires/GT6’s
wheels1986-89 DeLoreanThese are 14″ rims that fit on the Spitfire. They are fit the rear well but are too wide for the front (they hit the frame)
wheels (early Spitfire)late SpitfireAll Spitfires used the same bolt pattern (3.75″). Late Spitfire wheels, at 4.5″ or 5″ (1980) wide will fit early Spits.
wheelsTR75.5″ wide with same bolt pattern and offset.
Note: TR7 wheels are hubcentric (centered on the hubs) and Spitfire hubs do not allow this. It is a good idea to countersink the lug holes 1/16 inch to better accept the Spitfire’s stock tapered lug nuts.Check out this link for more info

bonnet staygas struts
Rover 214 (or 214i)orMonroe: 901002 – PB
My bonnet holder upper broke – rather than fix it I had recommended to me using 2x gas struts from above car. One on each side, mounting on the wheel arch (holes already drilled) and the chassis angle bracket for mounting the valances (you’ll need to knock something up with angle iron here). Works a treat and the bonnet will just about hold its own weight in any position.
See link for details.
bumpers (rubber 79-80 Spit)chrome bumpersYes, it is possible but front is not a straight swap. Details to come.
rear bumper (75-79 Spit)I removed the rubber “bullets” and the large center bumper cover and found a perfect bumper underneath. The bumper has holes but the can be filled with chrome bumper bolts from any 60’s car
bumper uprights (early cars)Standard Vanguard 1961
doorsMk3 GT6 doors will fit Mk4-1500 Spitfires and visa versaGT6 doors’ vents add much needed cooling to the cockpit, especially when the hardtop was in place. Interior parts of the door are different.
door strikers (early Spitfires and GT6’s)Austin Healey door strikersthey are the same as are used on several earlier Austin Healey’s.
window waist seals86 Toyota TercelMuch more substantial. Hold window tightly. Use inside and outside. Cut down to fit.
fender trim “bead”door edge protectorsBlack door edge protectors from Walmart can be substituted for the missing upper fender trim on later model Spits. One package does one fender perfectly. $2.66 per fender.
firewall/throttle linkage bushings (GT6 MkI)refrigeration compressor feetThe holes on eather side of firewall where the throttle linkage comes through the sheet metal. These rubber feet or vibration dampers from a 1/4 or 1/3 hp compressor are great replacements and are better than the set I ordered that were too hard to get into position (I even tried to heat them up to make them go into the holes to no avail. The compressor feet fit tight and with a little lube (silicone spray) every once and a while the will last a long time.

chrome rear license plate lamps (MkIV and early 1500)black rear license plate lamps (late1500)I found this out purely by accident. I decided to repaint the license plate lamps on my 78 Spitfire. I liked the chrome ones on the 77 model but I was being frugal and figured I’d just paint to old ones.
I started cleaning the old ones and lo and rehold,I started seeing chrome underneath. Looks like they were just painted over with black paint at the factory. I used lacquer thinner and the lamps are now shiny.

Rear Turn Signals (Round tail cars)MGA, Morgan +4 & 4/4, TR3According to this Morgan site the Stop (Tail) lights, Lucas 53330 – Model 549, of roundtail Spitfires were also used on Morgan+4 & 4/4 (59-68), TR 3s, and MGAs
Rear Turn Signals (Square tail cars)same as on “square tail” Stag’sStraight swap on “square tail” Spits
Rubber Cowl SealUniversal (weather seal)Use 3/8″ or 5/16″ black bubble seal,to replace (oem) full width cowl seal. Cut to size, presses right on. Gives a better watertight seal. Also use it to seal left & right front fender seals AND on top of window glass (L&R) makes a better seal against the hardtop. An easy-on (more effective) replacement.
I bought mine at ‘ZIEBART’ Co. OR NAPA. ETC. for $10.00 (20ft) approx.
Seat upolsteryOffice Max office chairsUse leather upolstery off chairs on 74-80 front seats. $30 / seat after rebates. Does not cover head rests and only comes in black 🙂
side marker plint (rubber holding chrome finisher and side lights) (Mk4-1500 Spits and Mk3 GT6)MG Midget 71+ (rear fenders only)Not a perfect match but Spit part is no longer made. Midget parts are flat and Spits are slightly thicker at bottom to compensate for body curvature.

Tail light mounting gasket (round tail Spits)58-61 Bugeye spriteThis is the gasket that goes between the body and the light assembly. The only difference is the mounting holes. Victoria British part # 8-822 Gasket rear stop / tail.
windshield (Mk1-Mk3 Spitfires and Mk1-Mk2 GT6 only)TR4/4A, TR5/250, TR6 1961-75All these cars used the same windshield
windshield (Mk4-1500)GT6 Mk3Mk4-1500 Spitfires and Mk3 GT6 windshields are interchangeable
windshield wiper stalk gasketLawn hose inner “O” ringTired of water running into your car at the body around the wiper? I used a garden hose O ring to fix the problem. You will have to take the wiper arm off and the nut and cover.
Windscreen washer jetRover 600 /AllegroI have an Austin Allegro water jet pump that feeds Rover 600 dual port nozzel jets. So I get 4 streams of water to clean the screen.

Rubber 1500’s to Chrome
Round tail:
Mk II and Mk III front bumpers are not interchangeable due to different mounting points. Mk1 & MkII bumpers have notches cut out of them that the MkIII’s don’t. Mk I and II which are interchangeable.
Rear bumpers will fit with some modifications, but keep in mind that Mk I and II cars had vertical sections to the bumpers where as Mk III models did not. There is a tail light lens in the location where the vertical bumper section would be on the Mk III’s. So you can put Mk III bumpers on any Mk I through Mk III, but you cannot put the Mk I or II rear bumpers on a Mk III.1500:
While possible, it does require cutting and welding (the bonnet mounting points are different and must be swapped also)
The rear bumpers of 1500’s are a straight swap.
Dashboard ClockMorris Marina / ItalGet a GT6 Passenger dash panel with the air vent cut out. The Hole is exactly the right size for a Smiths automotive clock. There are many different styles to choose from, go browse your nearest scrapyard. P.S. My dash clock keeps very good time!
door sealslate-model Hyundai ExcelDon’t want to pay for “furflex” factory type door weatherstripping? Go to a junk yard and look for Hyundai’s. Cost–about $10 for enough to do a complete car, and if you get a late enough model, it will look just like new (without the furflex of course)!
door sealslate 90’s Chevrolet S-10 pickupI used a set of late 90’s door seals from an S-10 to replace my worn out seals. Just cut to length needed and press on. I have a hard top and each door did enouth to cover everything side to side with some left over and stopped most of the drafts (like anything will ever stop them all), works as good as when new.
door sealsfrom JC WhineyPart# SJ819909N $17.99 ea, will need two (2) Flexible black rubber, much better then the cloth seals, and cheaper
GT6+ MK2 Ignition lockMGB“I bought an Ignition lock slated for 1968 MGB and it was perfect match for my 1970 GT6. Modification is only to remove the switch from it using the single set screw and swapping for mine… perfect fit!!! (you must drill the shear bolts from old switch to remove from steering column, better done with column removed from car.)”
hand brake gripMG MaestroThe original hand brake grip is not very good. A much nicer black plasticized rubber grip is fitted to the Meastro. To remove wait for a very hot day at the scrapyard and pull and wriggle till off it comes. Shorten grip by 1 cm. Heat with boiling water and slide over Spitfire hand brake. Result: hand brake now has a luxury feel.
rev counterAustin Apache TCThe Apache’s distributor uses electronic ignition and is a much better distributor than the AC Delco one originally fitted to Spitfires. It does not have the mechanical tacho drive needed for MkI to III Spitfires.
speedo/tach rubber gasketgarden pond pump gasketThe large rubber gasket that goes between the tack/speedo and the dash can be substituted with gaskets from pond pumps. These parts found in the gardending section at Home Depot type stores.
