1969 GMC Sierra with clean Title

Purchased the truck in October and has not been driven. All original, truck was tore down and repainted. small dent in the right side of the bed, no other body work that i could find. Motor runs and could use a little TLC. Belt, carb overhauled ect. Bed needs realigned on the frame. Plus the truck has wiring issues with the lights. Possibility of correct mileage because of the condition of the truck. Could even be original tires because they are nylon.
Have original air cleaner, nre fender wells not installed, new molding not installed and have the original mirrors not installed.
