Good luck with SGP and that fiasco. I canceled my order because of their error and they are still saying the lack of cutout on the flash does not hinder performance when others have posted pictures that it does. This is not a company I would want to deal with. Again, this is my opinion as I have had nothing but positive results with Power Support.
Call them about the re-cut backing because I received communication from them stating that last Friday was the day they were supposed to arrive with the new cutouts.
