Maybe you want to refinish it. Maybe you scored a nice Ralleye setup or want to customize it. Unlike the guy who claims you can have a glass in and out in 1/2 hour, changing a windshield, for me, is a gigantic PITA
Besides, reversing the screws is as "right" as anything else. The only reason the factory did it that way is because at the time it was easier, before the glass was installed.
