1979 GMC S1500 Shortbed, LS-1 350 swap 4L80E transmission with overdrive. Odometer shows 37500 miles, I can’t arrest this is 100 percent accurate based on the motor swap. I purchased this truck as it sits . Things I know are done because I’ve done them are new rebuilt transmission with less than 3000 miles, all new brakes, drums and shoes in rear, calipers and pads up front, new master cylinder, tires 200 miles ago. Starts, runs, cools, stops perfect. I would drive this truck anywhere. Very little rust or body issues. Interior is very very nice. American racing wheels, bed cover, bed mat, nice chrome. This truck scoots down the road smooth as butter. 80 miles an hour on the freeway feels like 50.
