1977 camaro rear

can someone give me the backspacing, spring perch and drum to drum measurements on a 1977 camaro? Thanks

I can give you a measurement tonight off my 78z. If you hit the forum over at nastyz28.com you will get an answer a little quicker.

If this is going in your 68 nova I believe the rear is about 1" to 2" wider than your stock 68.
