Found a second buildsheet in my car??

i have seen cars that had 3 or 4 of them hidden. even my charger had four. the build sheet mirrors the fender tag. there is a VIN number on the broadcast sheet. i have even heard of original cars with a misplaced sheet from another car in them. post a pic of your fender tag if you want it decoded. it will show whats on the build sheet. if you are looking for parts try posting a want add. cardboard headliners were extremely common.
