Actually,
I have done quite a bit of research on certain numbering schemes used by Ford and Saleen regarding build dates, VIIN's, and the actual serial number of the vehicles (this is actually called the Rotation Number). The VIIN IS NOT related to the actual build date or the rotation number. In most cases, it is close, but not accurate. The Rotation Number is the number to use.
The best way to know of this information is to try to find out if your dealer took any pictures of the vehicle before they may have removed the factory installed stickers. If they did, and you can get them, you will see what I am talking about. My work email is
rmartin@dh-inc.com and I would be happy to send examples of the factory stickers that your car MAY have had on it when it was shipped to the dealer. Ford initially had quite a few stickers on the early cars, then started reducing the number of stickers as production progressed.
Hope this helps.
