Seems like I've seen it done before, but I'm betting that it was custom painted in the same style, not the actual stripe kit. The stripes are shaped, cut and contoured specifically for the 1970 bodystyle and probably would not fit a 67/8 very well.
Honestly I never cared for the stripes anyway -says the guy with a bare e-cat. You should try to photoshop it and play around with it first. See if it still appeals to you then....blitz is right though, I bet you would have a bunch of trimming/shaping to make it look decent.
