Does anyone have the OEM part numbers for the rubber moldings (with metal backing) that attaches with several screws to the rear quarter panels to help seal the rear doors? The metal backing on mine is rotted and the molding is starting to separate from the quarter panel. Also, I want to clean up the panels where these mount and dont want to put semi rusted ones back on.

PS These would be for a 1999 Bonneville SLE.

Thanks for your help.

Best place I've found is Compnine.com

Thanks Bill. I was actually able to get the part numbers from Compnine (love their VIN decoder, too!) and surprisingly GM Parts Direct still has the parts available. For other members benefit, the parts are as follows:

25544906 */STR-R/D (passenger side rear door)

25544907 */STR-R/D (driver side rear door)

I have two Bonnevilles (1993 and 1999) and these moldings need replacement on both vehicles because the metal substructure to the moldings has rotted on both vehicles. Looks like a fairly common problem and the boneyards probably are in poor condition as well. Thanks again!
