So is this a guess or a fact? Does that mean it could be anywhere in that range or one of the 2? I ask because my dad is about to buy an overdrive tranny and we have a 65 Rivi rear end so we need to know. Thanks for the help.
The Grand Sport '65 had a 3.42 rear gear. The standard '65 had a 3.08. That's according to the GM literature. That said, I've seen a '65 with a 3.58 gear in it, but I think it was special order.
