I am going to go look at a 1956 GMC 600. Does anyone know any info on this size truck or where I could find info? It has the Pontiac V8, Dayton wheels single axle. It was a well drilling truck and the person who has it bought it for the drilling apparatus. It also has what appears to be an air horn on the roof so I am thinking it would have air brakes. I can basically get the truck for scrap value. The owner just wants it to go to a good home.
