“1949 CJ2A painted military green, but it is a civilian jeep. It appears to have been maroon originally. The transmission, clutch, and transfer case have all been rebuilt. It has a new intake manifold, exhaust manifold and complete exhaust installed. It has the original “Go Devil” 4 cylinder engine. 6 volt system with no turn signals. Starts and runs, carb will need some work. It has a clean title in my name. The frame is solid. Down side is it has a fiberglass tub.”
