The chrome tab will break off when you apply downward pressure onto it (“Denali” style shown, Mesh grille same). Once the tab has been removed, install the final lower mounting bracket.

11. “Denali” style and Mesh grilles: Carefully remove the protective masking tape from around the grille frame. You can pull up or down and left to right on the E&G grille or the factory grille shell to increase the gap where the stainless steel grille meets the chrome plated factory shell. Peel back the tape over itself to help prevent the tape from breaking and getting caught behind the stainless steel frame. Once the tape is removed, tighten the mounting hardware. DO NOT OVERTIGHTEN or you will indent the grille at the stud locations!
