Actually (and correct me if I'm wrong here Tom) 67 grills (as I've found so far) are a silver on the outer flat sections, they have a brighter silver ring around the inner grill and the center bar (or under the Chrome hockey sticks on 400's)and the center grill section is a dull black.

On the 68 grills the flat outer sections are a dark charcole, the silver ring and center bar, and the grill section is a dull black.

At least that's whet I've found on as many of the "unrestored" 67's and 68's so far...
