I need to replace the driver side rear window seal as mine has ripped. I already have a new OEM seal from Volvo. It looks like I have to remove the small interior trim panel from which the seat belt comes out. Can anyone tell me if this thing pops out or do I need to remove the large side trim panel, which would mean the seat has to come out? Any ideas, comments, questions or concerns would be helpful. The vehicle is a 2008 C70.
