The order number is on the window sticker. Bottom of the page in the "Item #" box. The four characters after the dash. I believe I read somewhere that the date on the bottom is the date the window sticker was generated until the vehicle is actually built, then it's the built/finished date.What do you put in for the order number when you do that? Is it shown on the inventory list? I think the mfg date/week shows on the bottom of the window sticker, right?
