Joe, are you talking full replacement/upgrade, aftermarket grille, or billet insert?
I think anyway you look at it the answer is no without a hood and grille shell swap, like theBac said.
The hood on 03-04 has a cutout to allow the hood to go around the grille, so to speak, where the 05-07 are straight across (hood sits atop the grille)....I think this is where the problem will be with the fit of any 05-07 designed product.
