Seems like a pretty scientific part, so here is a visual... (Obviously not my car, but this one is prettier and you get the idea) My car had an 'incident' that left it with a bit of cosmetic damage. So I need a window retainer for my passenger side (part #: 63531FE021). It is the metal piece that runs the length of the passenger side windows and holds the window gaskets in place (circled on the car above). I am not worried about the fading on it if it is used or anything, it just has to be straight. Let me know if you have a 02-07 sedan you are parting out, or if you happen to have one of these bad boys lying around, I would like to get mine fixed so that my window will seal properly. Thanks!
