WTB 8 3/4 backing plates/hardware

Sorry. BBP for an A body. I really don't care what size at the moment. My rearend went out on me, my truck tranny went out and I am driving a companyh car right now and they want it back. I am in a bind so any size is fine. I already purchased the disc brake stuff plus the adaptor to run the 11.25 rotors so the rears won't be so important. My blown up is a 7 1/4 I've been buying parts for this 8 3/4 as money allowed, I just don't want to put anymore money into the 7 1/4 when I'm getting ready to swap it. Thanks

Is your 7 1/4 also big bolt pattern with 10" brakes? If so you can use those parts. You may have to drill one additional hole.
