Verrry carefully! OK, that doesn't help you much. The moldings over the side glass and around the back glass will have to be removed, although probably not completely. You'll find that the vinyl is probably glued under these moldings-use some heat from a hair dryer to soften the adhesive before you pull if it's stuck. There is a steel clip near the center (same as door panel clip) that you should reach in with a pry tool to disengage. If you pull the panel, the clip will tear the cardboard.
