It seems to me that the driver-side opening is cut down a bit, as if someone had tried to replicate a prototype jeep?

“Selling my 1950 Willys CJ3A. Mostly all original! 134 flat head engine and all drivetrain are original. New leaf springs provide a little bit of lift over original height. I’ve been working on this for a few years and just don’t have the time to finish this. This does run and is drivable but it’s been garaged the past few years and maintained. Plenty of new parts already installed and more parts waiting to be installed.

New parts include: leaf springs, shocks, BFG mud terrain tires, water pump, carburetor, spark plugs and wires, all new brakes (wheel cylinders, lines, master cyl), engine and drivetrain fluids/lubricants, and various other parts like gaskets and windshield seal when those are ready for installation.

Fenders, grill, hood, windshield frame and tailgate were all media blasted and primed. Have been working on the typical body problems found with these old Willys.”

UPDATE: Still Available.

(11/10/2020) Lots of mods.

“350 Chevy powered classic flat fender. Muncie SM420 4 speed transmission (granny low,) Spicer 18 transfer case, full width Dana 44 axles with air lockers front and rear, onboard air, forged aluminum wheels (incl spare), one piece hood and fenders for much easier engine access. Those are the big upgrades, but there are lots of others – too many to list. The front seats are shabby, but I have a set of good condition, cloth seats from an early model 4runner (the ones that had a physical therapist on the design team – wayyyy better than the Ricaros.) Also have a spare SM420 (no, I don’t want to sell it separately) and a full cloth top. As you can see, the paint needs some help. The floor pan has all been replaced with heavier gauge sheet metal, but it’s also due for fresh paint. Runs strong, but could use a carb expert to get it dialed. Had to move in with elderly parent and don’t have room or time for all the toys, so it has to go. The best way to get in touch is to email me your phone number. Offers from people who have not come to take a look in person will be ignored. Clean CA title in hand”
