It's just pin striping. Find a color combination that matches, remove the old one and install a new one. Pinstriping came in options and varied from model year to model year. Whatever you choose, It will look great.
If you're looking for the exact size and color combinations, you will probably not find it. If you do, it won't match what is there due to fading. You're going to need to replace the entire pinstripe anyway.
