Sorry , I've been away from the computer. The New windows will ONLY work with the New Tops that Jeff and I are going to start selling shortly. They will not work with any other top made including our Double Bubble Tops. The seal at the rear door pillar should work well as it's worked fine for my personal top. The biggest benefit to these New windows will be the "Sleek Look" and ability to make these New Tops useable. Everyone isn't a fan of the "Double Bubble" hardtops so now there will be another option for people to consider when it's time to purchase. I'll post some more "Window" pictures on our website this afternoon......Thanks!!!
