Questions About installing a 93 Z28 Posi Diff into my 91 Formula.
I have some questions about swapping my 91 formula diff for a posi unit out of a 93 z28. Will it work? The axels are both 28 splin i was planning on using the original ring and piniion set.

I don't see any reason it wouldn't if the spline count is correct. They're both 10-bolt housings with a 7.625" ring gear.
