i pulled out the rear seats and i did not find any buildsheets. anywhere else they might be?
i have the vin and fender tag for the car.
Broadcast sheets are typically found:
Under the front bucket seats
Behind the rear seat back
Under the rear seat
Under the package tray
Inside the front seat upper covers
Taped to the top of the glove box
Under the carpet
I've heard of a few other strange places, but those I believe are the most common. If you do find a sheet it might not even be for your car. The Hamtrack historical site has a forum that attempts to reunite broadcast sheets with their correct cars.
