Thanks - it is a 61 C10- so far, the longest it has been driven is 150 mile trip from OKC to Wichita - did it on dry rotted tires, broken transmission mount, failing clutch and a wing and a prayer. The engine is stock - 235 straight 6. Three on the tree and seems a low gear ratio - on the turnpike with a tailwind it seemed as if I were flying at 65. Since bringing it home I've had the front end rebuilt and aligned, replaced the transmission mount, replaced the starter, radiator and throw-out bearing. New tires, and headlight wiring harness. I feel pretty confident, but haven't pulled anything with it yet. is wired for trailer lights - so perhaps it has. Brakes are good - not sure what to tell you on drive train - are you looking for gear ration of rear end? Appreciate your inputs.
