Jay, the dealer would probably outsource it to a glass shop anyway, so I would just work with Safelite to order an OEM windshield made by Saint Gobain which says "Sekurit" on the window. The aftermarket one is made by Pilkington. They both should have the radio antenna embedded in the glass. Make sure they put towels around your dash to prevent any scratches to your dash leather, and after they put the glass in, don't drive the car for a day or so, so that the seal sets right.
You gotta tell me where this "closed course" is.
