The VIN identifies your original engine size, and body trim level, but other than that, you have a blank slate.Just build it the way you want.
Are you stating that Dave Wise made you a tag with no Broadcast sheet to back it up?MMC made mine and had all options I put on the car plus color of vehicle. The two screw holes where empty on the inner fender so wanted to fill that spot. LOL. Build sheets came from the factory and many time are destroyed by critters or are lost over the years. Good luck. Build it like you want it.
