1979 Dodge D30 D series Mopar Ramp/Tow Truck Flatbed

1979 Dodge Ramp/Tow truck, 360 and 727 transmission. Run drive good, but make noise when accelerating or let off gas pedal. Im pretty sure it u-joints or carrier bearing (bearing in middle that hold drive shaft), should be an easy fix. I bought this truck to enjoy but have problem finding parking for it, so it for sale. Truck is beautiful, the flatbed is excellent, winch works good. The strobe/led lights function perfect and cool. I think radio work but I didnt care much about it. AC does not work.
Any question please call 703 853 0045, Andy. Thank you
