I tried looking around and can't find the answer so hopefully someone can help me out. I have a 92 Camaro RS 5 speed and I need to know what size differential I have. I know it's a 3.08 but the part I need to buy is a mini spool so I can lock my rear end into a posi and it's asking me about a 7.5 in or 8.5 in and I don't know what size it is. Thanks in advance.

Oh yeah, I will not be driving this on the road. Just the track. Just thought I would get that out there before some of you started to reply telling me it's not a good idea to use this part if I was going to drive the car on the road.

 

You have the 7.5/7.6 rear end.

 

You have the 7 5/8 rear end with 28 spline axles.

 

Thank you so much "supr_fly03" and "big gear head". I thought that was the size but wanted to make sure before ordering the part. Everyone has been so much help with answering the questions I have about the 3rd gen Camaro's. It's really nice to be able to get all your questions answered in one place. Kudos to thirdgen.org and all of the users.
