70AAR Cuda in Nevada help with valuation

I tracked down a 70 AAR Cuda 340 here in Nevada. Original owner is still hanging onto it, but I am starting to soften him up. He raced the car a few times many years ago.

Body needs restored, rear fenders were cut for racing and widened, original hood is missing. The original motor and tranny are long gone. It looks to have no rust and the interior is in very good original condition. Original wheels are stored with the car, but not on it.

What is a fair price range for this car? Thanks in advance, Troy
