“1952 cj2 has title runs and drives. Body is on a 56 cj5 frame. 5000 takes the running one with spare parts and the old frame as well as the cj5 body with no title for parts. Currently has antique tags and is road legal but needs lots of work as none of the lights are yet hooked up. Has fresh head gasket and got head shaved. 4×4. Fun to play around with but I don’t have time and were getting a side by side. Will entertain reasonable offers.”
