Question about a TSB...

[SatelliteJonny]

The Tsb that concerned weatherstrip maintenance, is it the rubber between the plastic cladding and the metal of the car or is it the weatherstripping around the doors?Kind of on the side, does anyone know what the cost of the plastic portion of the rear bumber costs, i was the victim of a parking lot hit and run, and while the car is fine, the bumber cladding has a slightly less then stock shape Thanks

If you need to replace the bumper, here's the cost and part number: (US $)REAR BUMPER88970429, Cover, Rear Bumper ($416.95)http://www.gmpartsdirect.com has it listed for $228.21Not sure about the TSB. Hopefully someone can clear that one up for the both of us. I'm assuming it is for the weatherstripping around the doors.
