pull off those "covers" between the header panel and the radiator support, pull out your headlites and corner lights. You'll see two clips on the bottom in the center of the grille, and two clips under each headlight location. Pull out carefully. Should pop right off. Mine pulls right off no problem. Of course those clips are still attached to the header panel...that's not how it should be. I pull the clips, then reinstall then in their spots on the shell.
Hope it helps.
