Dumb question for a dumb problem....I got a new set of cool chevy logo mats, but they have almost no grip and tend to keep sliding under the gas pedal. Im kind of particular about having my mats to stay put I could swear a long time ago I saw these little clips that hold your floor mats in place, but Ill be darned if I can find them anywhere ...google search came up with nothing....anyone seen these things somewhere?
