7 1/4 brakes work on a 8 3/4 axle

[71dart440]

Talked to Dr. Diff and he says the 74+ LBP 7 1/4 brakes will interchange with the earlier 8 3/4 rear ends (with converted LBP axles). Anyone have experience with this?

why just 7.25 brakes then? aren't all the lbp brakes the same? Dr diff should know that is his area of expertise. I have no clue? I only know that A body 8 3/4 were sbp with the 1.75 brakes & a goofy backing plate.
