Listed as a military 1946, the serial number shown is a very late 1947, though neither plates shown appear original. The tub may be a patched WWII tub. The chassis is from a CJ based on the PTO bar.

“1946 WW2 Willys jeep. The military version of the CJ2-A. Has front disc brake conversion, later model Go Devil 4cyl engine, brand new winch and led pods on front, aftermarket heater, Rhino liner inside and out. Runs but needs some carb adjustment because the mechanical fuel pump went out so I converted it to electric fuel pump. Needs new master cylinder (have new one in the box with 2 new front brake lines) looking to trade for later model jeep with a back seat, 4wd truck, big boy toys, pre smog, classic cars or trucks just lmk what you have to trade.”
