anyone have any 67- 68 rs grille rivets? there are two types. the flat ones rivet the plastic grille to the grille mldgs. the dome headed ones (which i need) rivet the grille mldg to the lower valance. my son had a playoff hockey game that went to a shootout, and i missed a box on ebay. if the guy that won that auction is on this board, i only need six.
