WIW 73 340 4 speed duster

hi all I need your opinions on what a fair price is for my one owner duster. a local guy is interested, but I'm really not sure what to ask. here is the rundown.

car has: original running 340 with 70,000 original miles, original 4 speed trans, power disc brakes with sway bar, fold down rear seat, dual exhaust with chrome tips, 340 stripe, original carb, radiator, shroud, 340 air cleaner, clutch pedal assembly.

car is missing: steering column, front bench seat, manual steering box, shifter, original rear is gone but has another 8 1/4 non sure grip

car needs a total restoration. both quarters, floor pan, rockers, deck lid, hood need replacing. frame rails are good except for near the rear bumper. doors are good. I would use the fenders. inner fenders are good as is the trunk floor. floor hump is missing in the pics but I have one. glass is all good as is the window trim.

I feel the car should be restored but I already have enough projects and dusters aren't my favorite anyways. I appreciate your input. thanks
