I just bought a 1976 3/4 ton 4x4 highboy. It has a little spot of rust on the bed just above the fender well. I paid $500 for the truck. It has a newly rebuilt 390 with less than 1000 miles on it. There is an automatic tranny in it. The carb gasket between the carb and the intake manifold is leaking. Do you know what a new gasket if going to cost me. And do you think I got a good deal on this truck?
