Technically KH front brakes are 11" so if I swapped in 11 rear drum BBP that would work well?
At the moment my car has the original KH brakes, proportioning valve, with a later small/large reservoir master cylinder, and SBP 10" rear drum.
I already have new Dr. Diff BBP rear axles, not sure which size rear drum would be better, but figured why not go with the 11 since I'm putting either 255/60/15s or 275/60/15s on the rear.
