The grills are installed the same way your stock grills are installed. You will notice that behind the grills, there are tiny little C-Clips clamped onto the bumper flanges. You remove the C-Clips and the stock grill will slide right out. Install Stazi-Grill and put C-Clips back in place. Make sure they are clamped tight and butt it up right to the grill so they don't flex or get blown off of the flanges from wind or any other debris. The oval is pretty tough to do, as I figured I'd try it myself. Getting the front and back to lineup, without the mesh getting in the way was a nightmare.
Also, I don't believe he sells the grills in any colors. You will most likely need to paint/powdercoat them yourselves.
