I have a 2004 Chevy Silverado 1500 LS Extended Cab with 8ft. bed and alot of water has been leaking into my doors and a little bit into the interior. So I think it is time for new weatherstripping only I dont know what or where to get it. Does anybody know where to get the outer door window belt weatherstripping, body/door jamb seals, and the window channel seals? Also does anybody know how to prevent water from entering the doors because I am putting in a very expensive set of JL Audio components and do not want them ruined.
