Slam panel codes..

I promise im not new to VW's, just new to the early German made GolfsOn one of my 78 cars, I have this tag which I believe to be the option codes. What does this tell me??

78 cars? That must be a record!

Well, you will have to excuse my english. I actually have 2 1978 Golfs and this tag is on the slam panel of one of them
