They are called Slasher Stripes as I recall. Gary has them, Sennaspirit had them. He used an aircraft quality silver tape to do his. I'm not sure how Valk did his. I've seen them in two tone if you really want to get fancy. LTD stickers? What you can do is go to the Karmann corperate site and send them an e-mail how much you love your Crossfire and would like their stickers and badges. They are real nice about sending what you ask for.
