Have you thought about just keeping your dashes bespoke for whatever the customer needs? Case in point is that I know a guy here local that does custom car work. Not your normal stuff, but some serious stuff where MLB players will go and buy a McLaren and drive it over from the lot and ask him to gut the interior and "make it their own". He only does high end stuff. I think your product would fit into this market nicely, and you could likely charge 60% MORE than the other guys, and these people would pay it to have something that no one else has. If you are interested, let me know and I will put you in touch with this shop. They do some amazing work.
