Crispy,
I followed your lead and emailed Karmann in Germany. Customer service email address. I told them how much I love the beautiful Crossfire that they built and asked for some decals, badges or build plates. They sent 2 of the blue shields like you have and 2 KARMANN decals in white letters. Probably would be best on glass I assume. I have not applied ant to the car yet. I will wait until after it's detailed professionslly.
