A Body LARGE bolt pattern rear brakes

Bill if you are converting an 8 3/4 rear to LBP you MUST replace the rear brake assembly COMPLETELY ... backing plates and all .... , the 73-up setup off the 8 1/4 is the same as the B body brakes you are asking about .

Thanks, John. I didn't know that. Exactly what I needed to know, and good information!!! I appreciate it.
