Here's another idea that requires NO CUTS or any other modification to the car...
Mount the Vette-Air to the bottom of the aluminum impact bar (drilling the front flat part of the Vette-Air and tapping a few holes on the lower side of the aluminum) with the scoop going up behind the bar. Looks like there's enough room to do this easily. Should have minimal impact on radiator cooling as this car runs cool (water wise) anyway. If I had a G3 this is what I'd do....On sale now for $90...
