73 duster shell what's it worth ..

Not for sale just exploring some ideas...
73 duster shell... Title of course, rust free, no paint, glass good windshield newish, V8 kframe, nice grill, all good lights and lenses, 7 1/4 just tossed under to make it a roller, crappy roller rims and tires, no bumpers, no fuel tank, no seats, no four speed hump no 4-speed pedals no steering column no steering box and no heater no windshield wipers ...
A great rust free start canvas for someone who's not into body work...
Again not a for sale thread whatsoever just thinking of ideas...
A good ballpark estimation would be great?...
