Pretty impressive weight. My 64 has a mega block making it heavier. But other than that it has moly cage, moly tube steering shaft and strut rods. Carbon fiber bumper brackets and hood (no hinges). Drive shaft, radiator, 5 gal cell are aluminum. Lexan (except the windshield) and no regulators. Light front seats, no heater, wipers, or back seat. Willwood's, Dana, Ladder bar , 727. All the rest of the sheet metal, floor pan, and frame rails are stock. With no fuel or driver it is 3100. What else did you trim?
