“This is a basically sound Jeepster that needs work. I put in a rebuilt Jeepster Jim transmission, but it still needs to have the engine wired before it will run. I am including a new wiring harness for the entire vehicle. This is the four cylinder Jeepster and ran fine before the wiring deteriorated. This Jeepster will have to be towed.”
