9,815 mile 71 Demon 340 6-Pak Mr. Norm Survivor

The window sticker would show the car being shipped to Grand Spaulding Dodge. Other factory-dealer paperwork would have existed showing the car was sold to GS Dodge. Order confirmation, invoice, etc. That kind of paperwork is valuable today because it gives provenance to the car, which commands a premium price having been sold at Mr. Norm's.
You are correct - I just sold my Mr Norms Challeger TA in May of this year. Larry Weiner (Peformance West in CA) has all the original Mr. Norms GSD paperwork for all GSD cars . For a $50 fee he will check your VIN # and if there is a dealer jacket for the car, he will deduct the $50 fee from the price of the jacket. Dealer jacket will have the advance dealer shipping notice (similar to the monroney label), misc assorted paperwork, copy of the original order, any warranty paperwork (if it came back for service) and sometimes an original set of keys. It's invaluable to have this paperwork to prove provenance for a GSD car and if like me you did not have a buildsheet, it concrete verifies what options your car originally came with.
