Hey, I bought a rigid industries 20" light bar for my truck(2010 silverado LTZ), and my first thought was to install it in the front bumper, above the license plate and below the grille. There's 2"x25" gap which I was told was like an air dam that allows cold air in to cool the radiator etc.. Now I'm having seconds thoughts and am thinking about putting it behind the grille. Has anyone else done this yet? If so, was it very difficult? Please share pics if you have em'
