Dumb question: Will anyone please share the part number for the correct diff for our application? For posterity?

That's the TrueTrac I think. Do you want that or the clutch type LSD?

Well, it's funny that you would ask that question. I did want the TrueTrac. When I ordered, Chris thought I wanted the clutch type so that's what he sent. Being that I was on the fence about which one to get, I decided to keep the clutch type. We'll see how that works for me. If I don't like it, I can always sell it and get the TrueTrac to put in one of the other diff cases I have sitting around

FWIW, I've only raced once or twice with the Eaton. The rest of the miles have been on the street and I have zero complaints with the Eaton. It's quieter than my OEM diff was in all scenarios except coming to a stop in neutral (get some "whirring" from the rear). I am on solid beam and diff mount though.

Mostly Eaton in here, but I'm wondering if anyone has a model year for the T/A Camaro or Firebird rear diff that fits. I know 82-93 or so, just wondering if I might be able to find one in a yard or part out. I have a few diff housings from the XR, might attempt to do the swap on the cheap to see if I can get it to work.

Thanks!

Here's the description from the Jeg's website. Says 10-bolt from '75-'89.
