The latest built 71 1/2 GT-37 I've ever run across, and in the GT-37 Survey, was a near identically equiiped 350 AT AC Fremont car. Basically, the same color combo, White/blue stripes 231 blue interior. Just so rusty in the 1/4's, at the time, just had to meet my Milwaukee sawsall
Did manage to save a lot of tough to find parts off it, so others could live on.
Good luck with sale, for interested buyers, car is still located in the SE part of the country?
