Have you looked on the frame rails for any stamped numbers. My 58 Chevy Suburban has the VIN stamped into the top of the frame right over the drivers front wheel. Might be worth a little time crawling around the truck looking for number somewhere else. I have no idea when they started stamping the frames. Maybe someone can provide some insight.
Either way, its a great looking truck. Appears to be in really good shape for its age.
