'67 's had black grilles with light silver surround. '68's had black grilles with argent (darker silver) surround.
The two colors are pretty close to the two silvers for rally II wheels.
Not trying to doubt you, but the FAQs say the black and siver areas were reversed between 67 and 68. I don't know who to believe! Could you verify what you said, please? I just want to get the facts straight.
