True 400 4 speed numbers matching cars are rare...hard to come by.

Second is the vert "issue" we have here..add that, even rarer.

Having the correct original body panels and floor pans solid, work with the originals, though they are dinged up. Spend the money on a great body man and have the original sheetmetal massaged and repaired. The doors and fenders..well...but keep the unibody as intact as possible. You will be spending quite a bit more for the extent of repairs to the original quarters, but IMO worth the expense.

Nice find! If you plan on buying it, it is better to keep the body as-is...and drive it..If you had to resell, you can certainly find a buyer for it as-is..rather than hack up the quarters and installing skins. Again, JMO.

Far as value, I say it's worth $15-17k. I will deduct $1500 though for the incorrect bumper and grilles (if PHS denotes a non 400)...original 400 bumper, original 400 grille inserts would run between 1 and 1.5k including freight/shipping. Therefore..13.5 to 15k as is. Add half the cost of the engine rebuild including labor, parts..so, roughly 1500-2000 I would peg 15-17k if the right buyer came along.

My opinion may change upon on hand inspection, but on it's face, 15-17k
