Nope, I'm saying remove the center front plastic piece between the front fenders and if need be, the hood too.  Then bolt the new air scoops in place of those middle plastic pieces you removed.  Make brackets on the new radiator shroud to bolt up where the fenders mount to the frame.  It wouldn't have to be big or goddy, just a shroud that flares outwards on the sides and level on the top and bottom with maybe a piece of aluminum running vertical or horizontal in the middle of the aluminum shroud.  Does that make sense?
