Iv put a set of Hasslers on the front of the 19 and would like to put on the rears but it seems the only set of brakes that will fit are the AC's If I install the Rocky Mountain brakes then I will not be able to use the rear Hasslers. Is there a aftermarket period correct rear shock that will work with Rocky Mountain brakes?
Perhaps just a few. Most accessory shocks 'overhang' the drum area by design for leverage.
The R-M Brakes have always had 'large drums', that extend well beyond the backing plate on the Ford.

Here are some styles of shock that perhaps wouldn't overhang the backing plate.
Maybe just go with accessory front brakes and leave the rear one alone
