I have a 1988 Chevy dually bonus cab for sale. Has a 454 big block motor with a 400 turbo transmisson. Has 62,000 miles on it. Runs and drives mint. Brand new tires all the way around has new heater core, heat works great also has a new battery. Has a new starter, radiator and radiator lines. Underneath has no rust at all. Frame is solid. And the bottom of the bed is in awesome shape. Awsome truck for a project needs rocker panel's done but thats all the rust this truck has.
