Interior Upholstery

I have a XR7 GTE, looking to redo the seats and rear window deck. Any suggestions on who has the best upholstery for white Interior? Are the rear window deck panel wrapped in anything or just painted?

The rear window package tray is painted masonite. West Coast Classic Cougar has a template for the package tray. See the link below with pictures of the package tray.
