Big white rubber wiring grommets. All i can find is black rubber. Is there such a thing? Nothing to do with wiring but been looking at a tube grill set up on my car today. Kind of got it sorted but need the right rubber grommets. What i have in mind is running the tubing through the front panel to secure it . i.e. no frame supporting it. It will vibrate if metal to metal.Kind of hard to explain without seeing it but the only issue is the finish the grommets give. Black grommets with look more obvious and white ones will blend in with the car (white) a lot better. Any ideas folks?
