You are looking at the 2.78 8.2 10 bolt posi rear from a 1970 Pontiac GTO. It is axle code WC. This is a Buick / Pontiac / Olds style GM A body 10 bolt rear with the bolt in 28 spline axles. Correct for 68 to 72 Lemans & GTO but will bolt in any 68 to 72 Skylark GS or Cutlass 442 as well. The carrier is a 2 series. The gears and unit look great. Housing is straight and not pitted or “hacked”. This rear is ready for you to add your brakes, fill with oil / posi lube and bolt into your car.
