Someone mentioned in previous post that I could figure out the rear gears in my 94Z by reading the build code. Where is it located on the car? I'm also looking at a 95 firebird for parts. Will the axle code be in the same place and will it be the same codes as the Z for 2.73 and 3.23?

 

Probably on the inside of the glovebox. GU2-2.73, Gu5-3.23, GU6-3,42. It will be in the same place.
