When did the "Certi-Card" program start?

I know for sure that they had it in 1965. I have one card for my Dart wagon I bought from Lance in CA. I also have a card from a 65 Chrysler. Picture enclosed. Is that the same card as 1968?

Second Picture is from a 1966 Barracuda that had the cards in the right inner fender. Which year did they had the cards in the engine bay?
