Spitfire 1500 Options and Changes

Note: This page may or may not be totally applicable to US spec. cars. For instance, not covered are the US emissions changes; there were constant revisions throughout the years.It appears that US cars received many changes that were later adopted by Non US cars possibly to ease in manufacturing complexity or to conform to European safety legislation updates.
Also, I (with lots of help from Joe Curry) have added a separate table discussing the Commission numbers 1977-79 to ease confusion regarding the model year, manufacture year and 1/2 year designations.Because info was taken from many sources, it may not be totally accurate. If there are any glaring inaccuracies, please 
email me.
