***7.25 brakes on 8.75 rear-end?*** "SOLVED"

DoctorDiff said
Unfortunately, small bolt pattern 7.25" backing plates will not bolt to an 8.75" rearend.

Cass has spoken! If he says its a no-go, then it's a no-go

My 7.25" is 10" drums (V8 car), if that matters any.

The problem isn't the size of the brakes, its the offset on the axles. The backing plates for the 9" and 10" drums have the same offset for the SBP 8 3/4 axles, so if one won't work, neither will the other.
