[COPO]

Rob, I have not yet learned which gears the car came with. I have talked with the guy who owned it from 1974-1991. When he purchased the car it had 4.88's. Years later he put in 3.55 gears. If I am able to talk with some of the earlier owners that's certainly one thing I will inquire about. You are correct, typically 4.10 gear and occasionally 4.56 on the COPO's. It is likely they were 4.10's originally and the dealer or a previous owner swapped in the 4.88's.
