I was wondering if anyone knows where to find a pinion yoke for a 3.23 27 spline 8.2 10 bolt rear end for an early 1970 GTO. The shaft size is smaller than the 1.4 inch 8.2. I have checked multiple places and no one seems to make them anymore. Some suggested to rebuild to 3.36. Any help would be greatly appreciated.

Good used is my only idea. A change to a 3.36 gear would require a completely different carrier assembly ($$$$$) and would be a downgrade for a street driven car. They made millions of these rear ends, surely you can locate the part with some detective work.

Are you sure you have bop gears??? what is your current set up? I ask because I had 3.90 gears and was going to swap down to 2.56 cruiser gears. I ended up with a 2004r trans swap and 3.08 chevy gears on 3 series posi carrier, I had to get a chevy yoke to fit the pinion. Plus I need a longer drive shaft and this way it will have standard u joints. The yoke fit all the bop pinions that I have seen, 2.56 - 3.90.
