C-30 suspension? Do dual wheel and single wheel use same front spindles calipers?

Hi guys, working on a 1963 Chevy Car hauler chassis, I have found a 1974 crew cab c-30 single wheel one ton with rebuilt 454 turbo 400 that I want to use as a donor vehicle. I plan on swapping the motor trans and entire font suspension onto he 63 frame, but I need to run dual wheels. is this a matter of justs wapping out front rotors or are the spindles, calipers etc different as well? thanks in advanced, john
