Re: camaro ss differential
4th gens have a 7.5" diff stock. Any speed shop (local or internet) should be able to supply you with the proper ring and pinion as well as an install kit. Your 6 speed car will have a 3.42 gear stock.
Richmond gears seem to not whine as bad as Motive does but they cost more too.
If you don't have the tools or the knowledge to do this yourself then I'd advise you to take it to a shop. Expect it to not be inexpensive.
