I can’t tell if theirs rust alone the bottom of the driver’s side of the body or if it is something else.The jeep has some mods.

“Beautiful example of a rust free, unmolested old Willy’s. All the right upgrades, but still very nostalgic and original. Shackle extension to give it a little lift. F Head motor, upgraded axles, new wiring, upgraded windshield, still 6 volt, new front tie rods and ball joints, tires, rebuilt generator etc…. Pretty sorted, a little tinkering, but runs and drives pretty darn good for an ancient relic! I was so excited about getting it and really wanted to keep it, but I’m running out of room and have another project coming. Has a good soft top and doors included as well as a few extra parts. Seats are in excellent shape, rear seat is a bit worn, but looks like it might be original as well. Starts right up! Come take a look. The market is all over the place on these, but I think it is fair and even a little under for it’s condition. I’ve seen them for more and I’ve seen them for less. I feel it’s middle of the road.”
