1969 pace car 396/325 fuel line clips

[CROSSRAMJL8]

I am restoring a original 69 Pace Car 396/325 with 67k. The double fuel lines clips are painted or coated with a dark olive with a brownish tint. I have not been able to match the color or to locate any information as to what color to refinish them and no one that I know reproduce them. There are several places that sell a reproduction clip but they are not the same design and they are a silver cad. I have included some pictures to show what mine look like.
Any help would be greatly appreciated.
