7 1/4 to 8 3/4 swap question about brakes

I'm not positive, but I think "it depends". Most, if not all SBP 7 1/4 brakes were 9 inch. These will not fit the 8 1/4 or 8 3/4. If the 7 1/4 brakes are 10 inch BBP, I'm pretty sure they will fit, if you use everything. Look at the number of mounting holes in the 10 inch 7 1/4 backing plate. If it has 5 holes, I think it will fit. If it has 4 holes, it will not fit.
