I am surprised that this is not a hot topic and easier to find info on being such a bad design. Does any know what the part number is for the seal that attaches to the driver door frame? I looked at gmpartsdirect and couldn't seem to find it. I guess the previous owner kept dragging his feet across it and wore it out. It is just a matter of time before the rear door seals wear out being subject to all the road debris. Yes I know you can get universal kits from sites like jcwhitney but they suck pretty bad. thanks for the help!
