Hey everyone I just received a67 GTA from my Father-in-law. I am going to restore it. The car was in an accident and the rear end was a Posi-traction. When it was fixed (by the original owner) they removed the rear end and put in a standard rear end. I have heard the Posi-tractions are hard to find. Anyone know where I can find one? Iam going to try to restore it to as close to factory as I can.
