“Willys Jeep CJ2A 1946 4×4 RUST FREE. This is the cleanest most RUST FREE Jeep I have ever seen. All original, has factory running board/ heater/ grill screen. Please look at ALL pictures to see exactly how rust free this is frame and body. Only rust spot found is under passenger floor brace – see photos. Story is truck was bought in 1946 used until 1957 then put away. Someone put a 12volt alternator on it and new tires years ago. I have brand new master cyl and 4 wheel cyl. Correct generator. New carb, new fuel pump and misc other items. Cranks over and has compression, should be easy to get running. Do not have title – I will provide bill of sale. Located in Zimmerman MN 55398”
