“My grandfather left me this jeep when he moved down south. It was parked many years ago because he sheared the shaft in the tranny down shifting. Motor did run when it was parked many years ago, but also have other motors and extra trannys, axles, and drive shafts, lights, buttons, seats, fenders… you name it I have it. The body is a 1952 and the frame is a later 1940s. Make an offer and lets make a deal”
