GMC Sierra 1977 Used Automatic Gasoline 4WD Chevy, size 20, double gear, automatic, model 77. Engine is 350, recently fully rebuilt by Hisham Al-Mulla's garage. Engine parts available for serious buyers. Gearbox is 350. Steel double, standing, working, and in good condition. Two tanks are working. Air conditioning is present but not working. All gauges are working. The vehicle is an American import and is clean. The vehicle is full, I can drive it near and far, summer and winter, and it's in good condition. There is a leak from the gearbox oil pipes to the radiator, and it's an easy fix. It needs polishing and some minor touch-ups on the body. The vehicle is good for a user.
