Not sure, I know 64-67 were shorter or longer (don't remember which) than 68-72.

No they wont the housing is narrower in 64-67 and as posted the top arms are different.I have a housing that will work if you wanna trade :)

First problem is the later frame brackets take metric bolts.

If it has a 12 bolt, then it already has aftermarket arms, or REALLY soft bushings.

Control arms are too easy to build to use the factory ones. If you dont have the means to do so, pm me and I will help you out. I have a jig and can do it.

A-body or G-body rear control arms are easy to build, and Edelbrock has an outstanding adjustable upper arm set for those cars for a couple hundred bucks. It enables you to properly adjust your pinion gear angle for proper driveline angularity. Those arms are so easy to build out of steel stock that there is no need to try and find the non-adjustable OEM type arms.if running in Stock or Super Stock, make sure the combination you arrive at equates the OEM wheelbase. Also, in Stock, adjustable lower arms are not legal unless the adjustments are made, the wheelbase is established, and the adjustment nuts are welded in place to negate the adjustable feature.
