What's the VIN and Data Plate info?
Jeb, your profile doesn't say where you are from. Even if you live in 'rust free" TX or CA, when checking on body work, always bring magnets. Especially if it's just been repainted. The flexible plastic refrigerator magnets are good, they don't scratch and are weak, if there's bondo they fall off.
Carpet is not difficult to get. They are listed in all the Cougar vendor catalogs. The dash pads held up pretty well on most 69-70 Cougars, you can find a used one or a cover from Just Dashes.
Don't generally buy a car with a 'salvage title' it's been wrecked or totaled. Some states don't require a title supposedly, just a Bill of Sale......I don't know much about that.
