I think the hardest part would be matching the color if you don't go with the Mopar replacement.
Otherwise, I could probably cut you out a set on the cricut for just a couple dollars. I've got a silver and white on hand. I've used the vinyl on other outdoor applications that has held up pretty good. We've got some on boats and trucks that have been there for at least 4 or 5 years with no fading or peeling. I've also had one on the barrel of my shotgun that is doing fine. Just shoot me a PM if you want to try that.
