With an ordinary vinyl stripe kit, you'll have a heck of a time keeping the edges straight because of the compound curvature of a Cobra's hood and rear deck. If you have a removable hood scoop it helps a bit, but if you don't then that's a whole other problem in it's own right. It may be doable with a really stretchable stripe material, but it certainly will not be easy.
The wrapping method using a large piece on the main hood area and then trimming with the cutting thread that Tommy posted might be the best bet for laying non-painted stripes.
