Be great to see you get it down to 3200-3250 pounds. I know the 1974’s are heavier than the 1972 duster and you appear to be slightly heavier than my son(190-200ish) but his duster is 3250 at the line. It is far from a lightened car with a heavy fiberglass six pac hood. Heater core, wipers and wiper motor removed, one race seat, one heavy redone stock seat of mine. (Rear seat is still in there) Spare wheel tub has been removed and replaced with steel. Roll bar and frame connectors, cal tracks And mono links. Everything else is stock.
