Actually, the build sheets looked different that that. The Buick-Oldsmobile-Pontiac (BOP) plants used one style (reffered to as build sheets) and most of the other plants used a style like what you found in your camaro referred to as broadcast sheets.
I think flint used broadcast sheets but these build cards were the only thing they stuffed under the seats.
It does not give as much info as a build sheet but is still a nice piece of documentation to have.
