“I’m selling my all original 1950 Willys CJ3A Universal Jeep with Power Take Off. Runs and drives great, clean title and registered in my name. The PTO works well, and it’s still running the original 6 volts. The frame is good and solid but some of the body pieces are rusted along with the under-seat tool box and muffler”
