Dave, thank you for the breakdown on how the cars came down the line and were built. It is very interesting stuff to read. As for Build/Rot Sheets, from what I am being told, back in the '55-'57 production runs, they did not have these sheets or leave these sheets in the cars. At least not by those names.
My new club member is interesting in obtaining as much of the documentation that is available for his '57 Tbird. A Gate Release and Accounting form, the window invoice, etc.. Just to have a record to display with his car. I now know who to contact, and that is The American Road Thunderbird Club (TARCT) TARCT invoices PO Box 363 Clarkston, MI 48347. They have all the available invoices for the '56-'57's and some for the '55's. You have to be a CTCI member to purchase them I understand. I will put him in contact with them. Here is their website.
