There was a book I saw at Waldenbooks ( and I think Barnes and Noble) some months back called "The Complete Mustang Restoration Guide". It is obviously intended for concours restorations but would definately have the info you need. You might try calling one of the tech hotlines at Mustangs Unlimited, NPD, or Mustangs Plus. They might even be able to tell you right over the phone. Sorry I don't have the numbers in front of me.
