Check out www.oldgmctrucks.com for Tech. Info., on your truck. I've never found a frame stamped number on any '47-'54 model truck, I've disassembled. Do you still have the "GMC Parts Idetification" Tag, on the back side of the glove box lid ? "HC" is just a model number for '47-'51 model Heavy Duty Trucks.
