Believe that all the turbo coupes came with 1st gear start tranni's, and longer legged diffs. Was surprised when the 81CD NA started out in 1st gear. The 81CD is in really poor shape, and I have only put about 100 miles on it. Front end is in need of complete rebuild/bushings. Tires shake bad enough to make it unsafe to test further. Will probably not do anything with it until spring, letting the $$ situation build up.
