You can be sure Hank that if I go & build it with a 90" wheelbase, the first day out in public there will be half a dozen "Cobra'' experts standing at the ready with Tape Measures in hand to tell me its supposed to be 93" or 95"
In the books 'The Cobra Story & Shelbys Wildlife' there is a pic taken in the 'New' Venice W/Shop. In the foreground is the Flip Top car sans bodywork, immediately above is the first 427 ( & only?) Comp car #98, & then an early GT40.
Interesting to note that The FT ran # 98 @ Nassau also.
Pic is not clear enough for me to decide whether there is any extra tubing etc, but central rear fuel filler is visible.
Would be good if it is longer as I could transpose all the suspension data I have from the TVR ( 95" wb & similar track dimensions ) into the build then & car would be real good straight out of the box.
