1973 Cheverolet C10 Cheyenne This is a rare truck because it's the first year for this body style, it has a TJZ engine suffix for California emission, came with factory A/C and factory option dual horns. Only the C10s headed for California in 1973 came with the TJZ engines. Has 342 rear gear, as was the option for the California trucks. There is some rust in the floorboards in the cab. Also, as pictured, the dash has a crack and there is a crack in the side of the bed above the passenger side rear wheel. This is a matching numbers truck. We have the original exhaust manifolds, air cleaner and heat shields. A/C works. Truck runs and drives great. We have much more info on the truck, but it is too much to list. Email with questions or to request more pictures or a video.
