Favorite or best Brand of Windshield Rubber

Looking to buy later front and rear windshield gaskets for a 67 Notchback Barracuda. At the same time switch to the later trim.

There seems to be a wide range in prices between Pro Kits and a couple other brands on eBay and Steele rubber. Anybody have a preference?

Also I want reinstall the back window, what gets the factory black sealant off the glass?
