I have a 12 bolt rear end from a '67 Camaro SS that I am rebuilding to sell. Axle code is QK 0405 G1 and the casting date is B157. This is a 3.31 Eaton Posi rear end. I have all new Timken bearings to go in it and new Yukon axles. It is sand blasted and ready to assemble. The traction bar bracket has been cut off, but I can install a new one if you want. I will assemble this as soon as someone wants it, but I don't want to assemble it now in case someone wants the traction bar bracket installed. I don't want to weld on it after it is assembled. Price will depend on how you want it built. two seven zero, five four three, four five five three. Call me for details.
