I quote Jerry MacNeish on this matter.

"All factory built non-rally sport Z/28s and 427 COPOs received an Argent Silver grille with matching headlight housings. Rally Sport Z/28s were equipped with a black grille. A black Z/28 rally sport would receive a silver grille. Only SS models without the rally sport package received a factory installed black grille"

Since this thread is about X77 cars it would be a sliver grille.
