This looks in good shape and most likely has a replacement body (not M-38).

“1951 Willys CJ-3A. M38 windshield and body. Starts right up, runs good, no mechanical issues. L134 flathead engine. Carb just rebuilt, brakes were rebuilt last year, new battery, electrical system converted to 12 volt, fluids changed regularly. Has some rust underneath but overall a solid old Jeep that just needs someone that has the time to spend taking care of a 70 year old machine. Title in hand”
