The inner felt seal on the driver's door window is a simple piece that wedges onto the ridge of metal. The replacement piece I got has an additional rubber lip running along it's entire length on on the inner side. I have been told that the part was superceded by porsche to this different style, but I am wondering if this is correct. If it is, I am wondering how this rubber lip sits in relation to the piece of trim that goes on the door-window sill (the piece that has a hole in it for the lock button) or if there is another piece that goes in this area. I am just generally wondering about how to install this part correctly and what it should look like when done. I do not have access to the car at the moment to give better description of situation, sorry.
