More than likely that paint can be duplicated by a local talented painter. But if you are set on getting the real deal, find here in the forum "AirBrushEd". you would be hard pressed to find one better. He was with the original BDM.
$$$$ but worth it for intricacy.
I would ask around locally. Word of mouth goes a long way and much easier to fix from a local guy than an online shop. Airbrush Ed is damn good. You get what you pay for but I would still try to find a local custom shop first. Good luck
If you go to bigdogpartskingpin.com on a laptop NOT your phone (for some reason it won’t show this on my IPhone 16) at the top of their webpage go to Tech Articles. Open it and scroll down to paint codes. This is what you will need to get you headed in the right direction.
