Those red bullet shaped plastic inserts are the right part. You may have to reinstall them a couple of times to get them to sit in there right. Make sure the pin on the molding is lines up correctly. The plastic parts get misshapen quickly if you get the molding pins off a little and try to push them in there. Also those moldings get a curve along the length that seems to make the pins miss the inserts, watch for that. May have to slide the pins around.
