True B body 8 3/4 housing

i'll check on my rear,get you some pix and also i have a set of 10" rear brakes...loaded and complete.

bbp 7&1/4 backing plates will fit the 8&3/4 too and are 10" x 2.5"
I will take a closer look at mine and let you know Mine are 73 A body 10x2.5, and I'm 90% sure they do not have the same flange bolt pattern that B bodies do.. - as I eyed them once before and they looked the same pattern as my housing's end's - not the B body style..
