I saw a theread of some prototype mesh grills planned for the Z. Just took a real close look at mine ... the current grill slats are part of the entire fornt bumper assembly. Unless you cut the grill out, Forget About It. If you're gonna keep your Z forever .. fine. But, if you'd like to put it back to original again ... no go. sorry guys/gals .. it sounded like a great idea/look.
