SBP 10" rear brake drums and shoes
cosgig, thanks for the number of the brakes fellow. I will definitely give him a call.
I have personally seen the non-flanged 8 3/4" drums on Craigs tables at the Nats, where I usually catch up with him. He isn't just a garage parts seller (like me!!), but has a business of selling brakes and suspension items for Mopars going all the way back into the 40's. When you talk to him, you would think that he has one of every model car in his garage and has taken the brakes apart everyday to keep up on his information. He really knows Mopar brakes, that's his business. Maybe I can get his flyer to load here.
As mentioned, he is a very unique individual, no internet, only phone and personal contact, but he will certainly help you through getting the stuff you need.
As for other 10x1 3/4" hardware, I think the offset of the axle flange is different between the 8 3/4 and 7 1/4, which would be the only other rear with the small brakes, but I have not confirmed that. I have a complete set of brakes I removed from a 7 1/4" SG equipped rearend, and am planning on mocking them up on an 8 3/4 to check the difference. I'll let you know my findings on this!! Geof
