Take it to a shop. The glass is a seperate piece from the actual vert top. You have to basically remove the back half of the convertible top to get to the staples that hold the glass piece. Once you get to the glass piece it's easy: pull the staples out, pull the glass piece taught, and restaple. But then you have put the convertible top back in place. Again have a pro do it. It'll probably cost $200 but at least you won't have any leaks.
