I've posted for this bumper before, too. No real good responses. The bumper mounts are different after the V6 model was introduced. The rear frame section extends outward through the hole in the bumper on later models, where the hitch plate is recessed on earlier models. You'd have to fab your own mounts for the 2-piece bumper.

Kim will be bringing the black rear bumper down to me this week, if you remain interested.
