You might give Phoenix Graphics or Graphic Express a call and see if they will make one for you. They dont have them listed but never hurts to try https://www.phoenixgraphix.com/ https://www.graphic-express.com/
Have you looked around? https://www.musclecarparts.cc/shop/...erick-grabber-side-and-trunk-stripe-kit/1534/ It says custom colors.
Graphic Express did some custom work for me in the past. I do not remember if they charged extra for that, but they were willing to do the color I wanted.
The two tone reflective white is actually silver looking. They will send samples for $1.00 each. Graphic express.
