Has a rear PTO setup. I don’t see a rear gearbox.

“For sale is an early 1949 Willys CJ-3A Jeep. First line of production in 1949. It has the original engine, .030, # 3J20935. Original Transmission, Tranfer Case and PTO, rear drive type, not for forward winch.
There is a body tag; #;19387 on the firewall just below the Serial # tag that was only used on very early production CJ-3A Jeeps.
Engine and maybe transmission will need to be re-built. Radiator looks good. Will have clear title.
This is a restoration project.”
