What's this creature worth

Hey guys, what's it worth? I would appreciate all your opinions, as usual. You are the experts. I was approached by a fellow mopar lover about selling his 69 f6 stripe delete gts. Non numbers matching( but period correct) 383, 4sp, 3:91 sure grip, title and fender tag, has had new rear quarters installed, the floors are good, all other body is salvageable, but needs paint and finished, it's been stored 20-25 yrs.it has new fuel tank with, but fuel system needs went through.What's this creature worth ???
Need a LOT more info (pics would be nice):
Engine/drivetrain- Running? Engine tired or fresh? Receipts? Original manifolds? Adapted properly to the 4 spd. (crank pilot)? Condition of trans./rear end?
Body & suspension- Frame rails okay? T-bar crossmember etc.? Original or rebuilt suspension? Modifications? All the trim included and in good shape? Glass all there and good? Inner fenders cut for headers?
Interior- Redone, good original, or rat infested? All the bits & pieces present and accounted for?
Electrical- New, decent original, or a nightmare cobble-job?
It all adds up, and it's usually the little stuff that breaks the bank. The current condition and amount of TOTAL work it will need to get it where you want it to be will ultimately determine what it's value actually is.
