The rear end that is in my 64 is out of a 72. Hence the 3.08 gears. It is a 5 stud axle, but I have 66 rear end with 4.10's and 6 stud axles. So I'll swap axles.
By the way, I cut out the rear engine mount out and cut the front engine mount down and will plate it in. This enabled me to put the 292 into it with a turbo 350. And if a 350 fits then a 700R will too. This gave me tons of clearance for the fan, but I think I'll still put in an electric fan to pull more air. I don't want any overheating problems ever. I'll post pics later.
