Fiberglass Body. Could be a Bobcat 3B body. It’s listed as a 1948.
“Willys high hood. Fiberglass tub and hood. Steel fenders, grille, and windshield frame. New gunmetal pearl paint. Buick 231 v6 with edelbrock carb and intake manifold. 3 speed transmission. Warn overdrive. Front disc brakes. Aluminum radiator. New seats. Soft with 1 small tear in back. 33’s with a lot of tread. Overall pretty nice rig but not perfect.”
