Seems the P72/P7C existed to the end but there is hardly any information on the net about them. A reddit user posted his ex-government 2010 P7C.

Has 2009-2011 side molding. Black rear fascia. Body color B-pillars. Crown Victoria! Rear badge. Honeycomb grille. Black mirrors.

I know Ford_Guy isn’t active much but this might be something to pass along to him.
