“Selling my 53 Willys. I just don’t use it enough. This is a 53 body, on a 58 frame. It has a Dauntless V6 out of a 67CJ. Lots of upgrades;
11 inch brakes with dual reservoir master cylinder, updated steering with a saginaw steering box, new tie rods, etc. All new springs and shocks. Engine was rebuilt 5 years ago and has maybe 1500 miles on it. Rebuilt transmission(T14) , transfer case ,and overdrive. Tires are excellent. Lots of spare parts included.
5:38 rear end so this is not a highway jeep”

Body looks in decent shape. It might be worth a look.

“1953 cj3b tub on a 75 cj5 frame. No title bill of sale only. Main components are there needs motor put back in tranny is still in the Jeep. Has 3 link in the front. With fox air shocks. The Jeep is definitely an off-road toy. Just needs put back together mainly looking to sell but will trade depending on what you have. Make an offer.”

Replacement body?

“New carb. New starter. New alternator. New battery”

The seller suggests that the hubs are self-locking, but they appear to be standard power-lock hubs from Cutlas (Cutlas did offer some automatic hubs in the 1960s … see the Cutlas Manufacturing history).

Maybe someone up north can use this?
