The rear isn’t looking like ’41 running gear to me. It could be a CJ-2A body. I’m not sure which parts are from a ’59.
“1946 Jeep Willys in good running condition with very little rust. 1959 Jeep on 1941 running gears included for a parts machine, but this Jeep could also be built up on its own. 770-784-1239.”
