Stillen ( http://www.stillen.com ) makes a grille for the Titan which can replace the chrome one on either the Titan or Armada. As a matter of fact, the minute you follow the link it appears in a picture at the top for SUV equipment. They also have a one-piece bumper cover for the Titan, but I don't know if it, too, will fit the Armada.

Good luck.
