Change rear Gear Have a 95 Trans am A4 with the 3.23s.
I am looking to go to 3.73s and have heard good things about the motive gears. I am looking for a good master install kit for my car
https://www.summitracing.com/parts/mgr-r7-5grlmk At first I thought this was the one, but it says fits 1999-present. Is this the right kit for my car?

Please see below for rebuild links. Yes they fit your car perfect. For the gears you want GM75373.
GM75410 is what you want. You're 3.90s were likely orange box Motives and they are known to be noisy.
Here's your rebuild kit with no wheel bearings:
