When did the "Certi-Card" program start?

Certicards were supplied from 65 to 68. In 1965 they came in the glove box, in 66 &67 there was a plastic holder in the engine compartment and in 68 there was a special pocket on the back of the owners manual. The cards changed a bit too. 65 was plastic with the name of the owner embossed. 66 thru 68 were aluminum with a semi clear Dymo labelmaker tape that had the info. just as seen above.
