I found a fourth gen rear available with posi, disc and a good gear ratio, but it's off a trans am. By just bolting in a fourth gen rear I would be able to run 17" wheels right, I was wondering though, whether or not 4th gen chevy f-body wheels would have the same specs as 4th gen pontiac f-body wheels? I've seen wheels on ebay in some places that they are different and wouldn't fit both. Any ideas?

 

4th gen Camaro and Firebirds are the same offset
