I have a couple of pictures of my restored dash on my website.
www.classicgto.com Click on the thumbnail picture of my plum mist 67. I had it plated at american plastic chrome, which I guess went out of business shortly after doing mine. Mr G's still does it. It was a PIA to mask and paint, but APC wanted $200 to paint it. The outer edge is semigloss black. Inside the bezel tubes, the overhang(where the speaker switch attaches), and the parts under all the knobs are the same color as the instrument panel. I had the inst. panel color computer matched, and mixed. It looks perfect.
