Oh boy that "Tomb" photo stirrs the blood.... Once you get the PHS papers maybe post a list of the cars you have so we can get a grasp of what your collection looks like. Something like my signature.
Year, Model, Trans, PHS color combo, maybe some key options....
Would be a very neat list, plus you will probably want the list for yourself so you can decide what cars to keep, and what cars would be valued higher. I have all my inventory on an Excel spreadsheet so I can calculate total collection value along with other data.
Hopefully the sheet metal has fared well inside the steel structure.
Last sugggestion is to sell the '70 Cougar first for sure.
