When ordering body parts will 3/4 ton
cab parts interchange with 1 ton cab
If there is a difference it would be the size of the wheel opening for the fenders, which shouldn't affect the cab itself. I believe 3/4 and 1 ton share same chassis (1/2 ton is different) so 3/4 and 1 ton cabs should be the same. Wherever you are ordering the parts from should distinguish what vehicles they work for.
