I am building a 1923 T Bucket from Total Performance, but i am using a rear end that i have laying around. Its an 8.5 10 bolt. It has GMC stamped on the ring gear and everything looked original inside. I rebuilt the whole rear except I cant find axle bearings for it anywhere. The seals i found, but the rear end is not a typical GM rear i dont think, this one does not have c-clips but i dont think there is an eliminator kit on it. I just think it came stock this way, there are four bolts that mount just behing the backing plate. The bearings i pulled out were different on each side. I work at a pep boys and tried crossing the numbers but i am getting nothing. I went to two bearing shops around my area and i couldnt find anything either. The rear end is a coil spring rear end, 5 lug, 8.5 ring gear, 10 bolt. Its got press on bearings and a collar that helps make sure the bearing stays in place, the seal is a double lip seal, which i found already. The housing itself had these numbers on it: 96, 1235197, CFD?, and 10. I dont know if that can help me find out what the rear end is from or not. The bearings have these numbers on them: BOWER R 1578 F and the other one was U1978ZJJ? I called Bower, which is now BCS and they didnt have a cross reference for that number. Any help anyone can offer will be great, i am so desperate to find these bearings. Thanks, Mike
