So I have a nice posi unit and 3.73 gears that I got for my 3rd gen Camaro. I sent the diff out for blast and paint but wound up picking up a '80 Camaro ( my true LOVE, 2nd gen !!). It has nothing for gears or posi and I wonder if its possible to modify the 3rd gen diff to fit. I know the coil spring perch is wrong but I could cut it off so the leafs will work ? I do have welding and fab ability so I don't mind doing it if its workable. Anybody have experience with this ?
