This has a DJ-3A body on a CJ 4×4 chassis of some kind. It’s listed as a 1953, but DJ-3As weren’t made until 1956.

“This little Willys Jeep has a completely rebuilt drivetrain, motor, trans, and rearends. Has all new brakes and aluminum wheels with like new tires. Body is a 1953 DJ-3A, solid floors and good shape overall.
Runs and drives great, racing seats, gas tank and battery mounted in the back. Still needs gages wired and a roll bar and windshield, still a project. No title, but these have the screw on ID tags. Buy a non-running old rusted out Willys with a title and you’re done.

Looking to trade for a 3/4 ton or a one ton pickup, or another Jeep, or cash works, asking $2200, Trade $2500.”
