Any billet grille made for the GT will fit the CS upper grille. Shelby makes the only one (that I know of) for the CS lower opening since the CS shares the same lower fascia with the Shelby GT. I have not seen any of Shelby's lower billet grilles, so I can't comment on how that one looks. Look at any picture of the Shelby GT to get an idea of how the upper one looks. One warning on the upper grille...you need to hack up your original grille in order to use it as a "backing plate" for Shelby's billet overlay. Not an optimal design IMO. I know that Shelby is currently working on this and they plan to release a new upper grille with its own mounting brackets. That way it'll swap out with the stock grille. Hope this helps...
