"Build Sheet."

Never found mine.

Nice reference:

Also the Chrysler Historical Society may have the microfilm of the original IBM card known as the Build Record. The build sheet is one of the first things manufactured off of this card. Pre-68 this may be another option.

I was able to get a copy of the microfilm of the IBM card, decode, letter and certificate from the society which also indicated the dealer.

My dealer was Marked Tree Motors, Marked Tree, AR. Still trying to figure out the original buyer. St. Louis, MO plant built.

Good luck with the search! Sometimes taped to back of glove box, (you can reach around).
