Probably this particular time of year, you might have a hard time finding one on the lot with wing delete. I don't think most dealers are getting many new deliveries so that they can clear out current stock for 07's.
I ordered mine with wing delete, it took just over 2 months to get it.
go to the dealer and have them search inventories for what you want. if there is one close, they can dealer trade for it and sell it to you. or you can go to the other dealer and buy it directly form them.
