I know that there have been threads on this topic in the past, but I just spent some time searching and couldn't come up with them. Anyway, I know that some have recommended using '86 F150 rear drums for F1 fronts which aren't available. So, I went to Rock Auto Parts site today and looked up '86 F150 rear drums and found a whole bunch drums, rotors, and what have you. The drums made by Centric have nice little drawings and the one shown below matches the pair of original F1 drums that I have in drum ID, height, bolt pattern, and center hole diameter. There's a very similar drum, but the center hole is much larger.
