1981 Manual Gasoline Peace, mercy, and blessings of God be upon you. I present to you a GMC Model 81 350 engine The vehicle has not been inspected, and the registration is new. The vehicle is running but has several problems: - There is a crack in the chassis, attached are pictures. The price is 21,000, and we are negotiable with a serious buyer. - There is a crack in the chassis on the driver's side, attached are pictures. I asked specialists about it, and they said it's a common problem with GMC users. It needs proper welding and doesn't affect usage. - There is also welding in the bed near the storage compartment on both sides. - The transmission has a clunking sound when shifting gears. It could be the clutch or the transmission. - There is a transmission fluid leak that needs seal replacement. It could also be the torque converter due to low fluid. - The vehicle has hesitation. I suspect the carburetor needs cleaning. Generally, several things need cleaning, like the radiator, given that the vehicle was parked for a while. The vehicle's engine is sound. I changed the spark plugs and wires, air filter, engine oil and filter with a solution. I also changed the starter solenoid. The highest offer is 17,000. We ask God for more.
