I would order a new one and replace it. If it's the rear quarter window, it's a PITA as it is held in place with adhesive tape. Stuffs really aggressive and it took me forever to get the part off with heat gun and dental floss. The residue cleanup was tough part really. If it's on the door it's really easy to replace. I'm looking up part number for you right now, so hopefully you will be able to get the part you need. BTW, the lower gasket trim isn't terribly expensive, it's the long one that goes over the top of the door to the back quarter windows that's expensive.
