GM part #20864530
Found out what this is. Basically its the rubber area that is under your windshield wipers and contains your washer nozzle's etc. The dealer put it on today and told me they have a bulletin out that the original one has a leak in it that allows water to run down into your strut casing and other suspension components and cause them to rust and make noise. Hence the parking brake cable noise. Hope it helps.
