Been Looking At A 67 Fury III...
2 door or 4 door? The slab side boats have a small following. If you're looking to flip it, as I read into your opening lines, I seriously doubt you'll make anything on it. Maybe ask the same questions on FCBO, or Cbodydrydock.com
That being said, if you're going to cruise it yourself for a couple of years and it's as clean as you hope it is, go for it. That thing will be a smooth ride for sure.
