UPDATE: Still Available.. I’ve never seen a step/fender setup like this. Makes me think it is fiberglass.
“1946 Willy’s Flat fender Jeep with a small block Chevy 283 v-8, 4 speed manual transmission, Duel range Warn transfer case, telescoping tilt steering wheel, bucket seats with harness, roll bar, Dana 44 axles and large drum breaks with heavy duty drive lines. Runs great. Body is in excellent shape.”
