Have a very rare 1979 GMC 3500 single wheel in very good condition. It has only 19,940 original miles and the paint and everything all original. No rust anywhere on the cab or body. Always stored inside in climate control building. I even have to original bill of sale when the truck was purchased new from the fire department. Has a manual 4 speed with 3.73 gears. The motor is a 350. I’m open up to cash offers!
