Had a fun day at the autocross today. Then I get home and my rear window won't go all the way up, great. My friend had this happen and the plastic was broken on his, it seems this is what happens to most people in the archives. With mine, there is a metal piece that I had to rotate towards the front(psngr window), it has a notch in it that is apparently held by a separate piece. This separate piece came off and looks like |______| from the side, it has semicircles on the end so that it will ride on the guide wire. How can I get this back in place? Or is there something that holds this piece that broke?
