Welcome to the forum!
I'm also looking for those stripes. So far it's a no go finding them. I have emailed a few of the companies that make the stripe kits and nobody makes them right now. One place said they would, but I would have to send them my entire body set for them to duplicate them for production. I don't have that kind of money for shipping.
I have come up with a possible solution but have not gotten to the paint part of the project yet. One Shot pin striping paint makes a color that's very close. If you add some of the gold they make to it, it just might be a match. The color #'s are 110-L metallic copper. Add 111-L metallic brass or 109-L metallic gold to it to tint. Most auto paint shops will have this brand of striping paint.
Good luck with the project. Let us know how you make out. Especially if you find the decals.
