I had them on my 54 two-ton. They had only about 1/2" or less clearance at the tightest spot. They fit the hubs right from 54 up too. Mine was single speed rear, think the 15" brakes? not sure on them. The earlier hubs are 1/4" smaller, so wheels are sloppy fit there. BUT, I'll either run that way or always wanted to see if shop guys could make a thin spacer ring to take up space, tack into the rim hole. Would need a lathe for sure. Only about 1/8" x thickness of rim, maybe another 1/8 or bigger, whew! Might not work. I wont' be loading mine much, so will ride on studs instead. I've seen even the older stock wheels used with-out fitting hubs on old farm trucks I have bought in past.
