how can you get one, where can you get one, and how much?
It requires a new rear bumper, paint, and a whole handful of screws, washers and stuff: http://www.ricambiamerica.com/product_info.php?manufacturers_id=&products_id=262661
not worth replacing on a 430 . . . if u want to order one, might as well just order it on a new car. installing it aftermarket may be quite a pain.
