Arctic-911

I'm looking for a deck (engine) lid for a 2006 911 4s with the "X51 Power Kit". I've talked to what seems like dozens of parts guys and keep getting 997-512-011-04-GRV. Unfortunately, this part # does not have the two air intakes that are need for the X51. No one can tell me how the original parts that fit actually came about. Was the extra intake cut out by Porsche for each X51 model once ordered by the customer? Doesn't seem likely, but maybe. I've attached a few images of deck lids with two air-intakes to prove they do actually exist. Any help or insight is greatly appreciated.
