Maybe an ex-Mobile Gas truck??

“1957 Willy’s Jeep Pickup, 6 cylinder, flathead, 3 speed manual transmission, high and low range 4WD, all new brake lines, wheel cylinders, and brakes, lots of new tuneup parts, plugs, wires, cap rotor, coil, and carburetor kit, all front lights work, tail lights need to be hitched up, frame is very clean and solid, runs and shifts good, new upholstered seat, was planning on restoring but to many other projects, must sell. Would be a great restoration project or drive it just the way it is! Tires hold air but are weather cracked, truck bed is also in good condition. Serious inquiries only. Cash only. May consider trade for muscle car.”
