You'll need to look at the option codes on your RPO sticker. This sticker is usually on the inside of the glove box door, if equipped, or the underside of the spare tire cover, or the underside of the console lid. It will say do not remove in large letters at the top. You'll see letters and numbers in groups of three. Those are your option codes. Look for option code B4Z. Hope that helps! Jim
