I want to put on rain guards on my 2004 Chevy Silverado. It is a non extend cab. I need to know how brands are the best price is not that much of a factor. Also how strong are they, are they strong enough to take in to a touch free car wash that has very strong water pressure. I would rather buy them in a store than online, so where is the best place to buy them I.E, Pep-boys, Auto-zone, Advanced-Auto,
