LS-6 Chevelle Build Sheet Location

[blackls6]

My LS-6 was built in Atlanta and I found one of my build sheets in the passenger door panel. The owner I bought my car from had another build sheet, car shipper invoice, protecto-plate, and second owners title! I talk to the original owner once in a while and told me his aunt worked at the Atlanta factory and he got to see his car being built.
How cool was that!!!!!!!!!!
He told me one of the door panels had a Malibu plate.
