Can the Silver foil sun shade in Dometic Acrylic tilt out windows be replaced?

[bcolins]

I have a 2004 Gulf Stream Vista Cruiser with Dometic Acrylic tilt out windows.  The silver Foil Sun block/ privacy screens are in bad shape, and I am wondering if this material is available anywhere.  The interior roller that the sun block screens are attached to remove easily,....thinking that someone, somewhere offers a repair/replacement kit for these.  Any suggestions?
