For rigidity, the Carriage Works upper and lower billet grille inserts were fastened at the center of the grille shell on the backside. Note the supplied L-brackets (shown), which hook to the grille and are bolted to the plastic shell with 3/8-inch silver screws. For these mounting points, it is important to only drill through the first layer of plastic on the grille shell. Otherwise, you will drill through to the outside of the grille. A 3/32-inch drill bit is recommended for making these holes.
