floor piece in the trunk. This is piece of wood like material covered on the top with the trunk carpeting. (The piece that covers your spare) You will find a little white sticker with the build date on your car.
You can also call Ford with your VIN and they will give that info to you...for freeeeee
I lost the authenticity card that came with my '04 Cobra. After much frustration trying to get info from Ford, I called 800-fordstv. After I gave the customer service guy my vin, he gave me the build number and the build date. He is also sending me an authenticity card. If the card is a replacement it's $40. If it's your first request, it's free. By the way, they answer the phone "Ford Performance".
