“1957 jeep cj5 with a 2 cylinder duetz diesel , runs and drives has very little brakes , body is very very rough has original m38 style hood , newer fuel tank , Ramsey winch works , no title but can write a bill of sale , bought as a project but am moving and don’t have the space to take it with me”
Too bad there’s no photos of the engine or any word on how it performs.
