I picked up a T-Rex billet grille for my lower valence that is getting painted today and was wondering how to install it. It looks a little odd and the directions aren't very helpful. They say to "Center the billet in the bumper opening. Fasten the billet insert to the factory holes using the hardware supplied." But I was thinking what factory holes? If anyone has a billet grille in their 01 - 03 lower valence please help me out. Thanks. Here are some pics to see what I'm talking about.
