This may be a CJ-5 chassis with a fiberglass body.

“Accepting offers on my Willys jeep. Titled as a 1962 Willys, it has a CJ2A body tub with a 3A windshield.
Body is fiberglass so no rust issues. Has a Dauntless V6 225 motor with a Saginaw 4 speed transmission.
Recent work done includes:
New wiring harness
New gauges
New taillights
All new brakes including master cylinder
New slave cylinder for the clutch
New CJ5 fuel tank converted to underside
Rebuilt carb
New DUI distributor with 10mm Livewires
New mufflers
New seatbelts
Has full soft top with doors in great condition

Fires right up, everything works. Needs a little TLC to be finished but fun to drive as-is. ”
