The seller believes this is a prototype CJ-6 body.  Perhaps someone can take a closer look, as I am no expert on CJ-6s.

“Early 1950’s Jeep CJ6 body tub (this one is similar to the M170 ambulance)

I think this is a prototype body made between 1953 and 1955 after the military version but before the civilian version was released. All tool boxes are factory items, it has the passenger side drop where the spare tire was located in the military version – but there’s a toolbox lid on it. It does not have the 24volt connection on the passenger side, it does have the “JEEP” logo on the side. Included with this body are the dashboard (original plus one that was installed over the top of the original), the steering column, and the cowl vent lid. The dashboard is taller than other CJ versions by a couple of inches. The left side of the dash has a glove box (you can see it in the picture) with the lid. I think I’ve still got the taillights for it as well.

It also comes with the 50 gallon large fuel tank under the drivers floorboard (you can see the filler housing on the left side behind the door). I think this was a military-only item as I’ve never seen this tank in a CJ model.

Unfortunately some previous owner torched this body off of the original frame, and cut the bottom of the steering column off as well as some body mounts. Everything is repairable, and there is only a little rust (though there is some bondo in the passenger side behind the door). The body looks straight – it’s about a 20 footer if it were painted.

I have a few other willys and jeep parts available – 86 CJ7 body with windshield, 6 point rollcage for CJ7, willys truck body and frame, cj5/6 heater vent plenum

If you’re looking for a CJ6 body this is a lot cheaper than the Omix-Ada bodies out there – plus it’s got some unique features.”

“I have for sale a nice Jeep CJ6. A CJ6 has the same parts as a CJ5, but is 20 inches longer. Ideal to make a Scrambler which is only 2 inches longer. Jeep has 4 cylinder F head 3 speed. Very nice tires, two (2) extra front fenders and a very nice extra windshield frame with glass. No front seats, no battery, but has a back seat if wanted. Also has a rollbar (not pictured). Jeep runs with a temporary electric fuel pump which I removed and purchased a new manual pump (not installed) Jeep ran off of a fuel can, but a good fuel tank is included. Good title. Need more pics or have questions no problem. Can be seen at 6917 Rt 152 6185423668. Reasonable offers considered. Possible trade for a early to mid 60’s Ford truck. UPDATE//////// INSTALLED THE FUEL PUMP THIS MORNING, RUN HOSE INTO A JUG, JEEP KICKED RIGHT OFF AND RAN NICE. JUST NEEDS HOSE RUN TO FUEL TANK. BRAKES NEED WORK BUT RUNS AND DRIVES”
