certi-card

my 65 service card is riveted to the door of the glovebox.

That's not the Certi-Card. The Certi-Card was an embossed card the size of a credit card, that could be run through a credit card receipt machine (you know, with carbons -- remember those?). It was a "hi tech" way of recording the owner information when you went to the dealer for service. They were kept in a plastic pocket which was snapped into the inner fender with plastic pins, near the battery. Because they were loose objects, and because they had the original owner's name and address information on them, they were almost always removed or discarded when the car was sold. If you bought a car from the original owner, it might be with the paperwork (mine was).
