Rear axle out of a 67 Buick Riviera, same as GP?
 

I have this rear axle, removed from a 67 Riviera. I dont know if its the same as a GP? 3.07 NON POSITRACTION. Code on Axle Tube PJ. This was pulled in exchange for a POSI axle . Backing plates, front pinion flange are on. Front pinion flange is flat, so the driveshaft yoke assembly bolts on. No noises or issues. $150.00 takes it.
