hey i was wonderin if a limited slip out of a 4th gen would work in my car. also it has 3'23 gears with it would that and the limited slip be bebetter than what my car has stock?

 

All depends on what your car has in it now. I think the 4rth gen posi stuff will work in the later 7.65 rears, not sure about the 7.5
FWIW, the 4th gen rear assy (whole diff) will bolt into the 3rd gen, but be a bit wider...have you checked in the drivetrain forum ?

 

thanks for the advice i forgot about there
