Several years ago Bruce Ponti had a bunch of correct, square-eared posi-traction plates and frictions made for the 10 bolt corporate 8.5" GM rear end with carriers 410408/410409 (S- spring only) because the GM supply had all but dried up. They're believed to be a bit more of an upgrade from the original GM stuff in that they're a tad thicker than stock. They replace the GM p/n 231127. And unlike the GM stuff, they come with a shim pack as well, and free advice on any questions. Note: These do not fit the Eaton carriers, the ones with the little coil springs.
I think a couple of rear end companies were selling some sets for a while, but they quit doing parts sales because they made more by selling complete rebuilt carriers. Are these any better or worse than the round ear versions? I dunno.
When they were first available, I felt I wasn't going to rebuild the rear end in the 85 442. So I didn't buy a set then. But crossing fingers without much hope, I did end up emailing him recently and was surprised that he still happens to have some sets left. So if you need a new posi clutch pack for your car, he probably can help you out. Just toss him an email. I have no dog in this hunt other than buying a set myself. Just passing this along.
