Fender Tag?

You will never know if any (or how many) broadcast sheets are in it if you do not look. So, here is a list;

Taped to the back side / top of the glove box insert.
Under the front bucket seats in the springs (or under the front bench seat)
Under the rear seat bottom
In the rear seat back.
Under the package tray (speaker shelf)
Under the carpet

Best of luck!
