How about a pickup "certicard"?

This is the only one of these I've come across. I'm sure there's more out there but, for some reason, I haven't seen another. Not even sure if they still called them Certicards or not, or even if it was used nationwide. It's bare aluminum and I'm not sure what some of the codes and numbers represent. It's for a 1971 D100 with a 383 engine. I thought they had discontinued these type of cards before 1969. Anyone else have one and know more about them?
