This is the secret to installing the glass and seal. A piece of cord about 15 feet long will do the front, obviously the small back, and will also be enough for the big back window. Starting at the top, tuck the cord into the slot in the seal and work your way around the seal to meet back up where you started. With a couple of buddies to hold the glass, install it from the inside, into the body opening, pull on the cord, one side at a time to fold the seal over the flange in the window opening. When you get to the end of pulling the cord, the window will be set in the opening.
