7 1/4 To 8 3/4 drum brakes
For A body 10" small bolt pattern rear brakes the parts interchange between the 7.25 rear and 8.75 rear brakes is everything EXCEPT the backing plates.
Offset and axle mounting flange are different.
One plate WILL NOT bolt in place of the other.
part numbers for shoes, wheel cyls., etc. are the same for both.
8.75 axle shim placed over 7.25 small bolt backing plate. Makes it a pretty obvious no-go.
