4900 windshields

I was wondering when they changed windshields from a rubber seal to being glued and if I could retrofit the glued windshield to the rubber seal? I am on my third windshield for the driver side and the second on the passenger side within the last year. A lot of the installers are hacks and it would be nice to just have one with the rubber seal to put them in myself without having to cut the adhesive. Also, the local glass place has an option for a heated windshield which would make a nice addition in the winter since the defrost system sucks on the truck. I usually have the option of a clear windshield and frozen side windows or vice versa.
