1951-54 Chevrolet passenger & 1953-62 Corvette are the only front hubs that will work on the
1952 1/2 ton (the earlier ones only fit cars with "huck" style brakes) as for the 6-lug brake drums they fit like from 1951-1970 pickups. The 5-lug drums fit Chevrolet cars from 1951-58 front or rear and 1951-70 rear.
