Normally, I wouldn't think of arguing with Mark on Spitfire suspension
stuff. However, the early "squaretail" Spitfires with swing-springs (1971
and 1972) still used the same length axles as all Spitfires (and Heralds,
etc.) that came before). It was not until the 1973 model year that rear
axles were made 1" longer, resulting in a 2" increase in rear track.
