This has a meaty rear bumper with a Ramsey100R PTO winch installed. It also appears to have a replacement body.

“Late 40’s early 50’s Willy’s CJ3a for sale. Body has a bit of rust. It appears to have the Dauntless V6, power steering and brakes. Not running but the previous owner said the engine is not locked up. This Jeep has a Koenig 8k winch mounted on a big back bumper that is mounted into the transfer case. The winch itself is worth about a grand. If no one buys it now, I will rebuild it and sell it finished after I finish a 67’ CJ5. Feel free to ask any questions you may have. Only Jeep related trades, and no low ball offers. Bill of sale only. Front two tires not included. I have some beater tires/wheels if you need them to haul this away.”
