11 Inch Rear Drums?

The 11 x 2.5" LBP brakes on a 9.25 are the same big brakes that were used on the 8.75 and Dana rearends and they will bolt right uo to an 8.25 as well. You will just use only 4 of the mounting holes instead of all five.

Those brakes can be found on C-Bodies, Hi-Po, BB B and E-Bodies, 3/4 and 1 ton trucks and later B-Bodies like the Cordobas, Magnums etc.
