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.”
