The 7 1/4 has a flange to flange of 53.2" and the 8 3/4 is 51.4 (I measured the one on my shelf at 51 15/16"). But remember that the flange to flange doesn't mean that you'll have that difference in clearance. The drum to drum could be the same even if the flange to flange is different due to brake size/axle offset. The best bet is to measure the width drum to drum.
