I was traveling at a brisk pace when a large truck passed by in the opposite lane. The resulting gust removed my SS windshield trim piece over the top of the glass. This being Oregon, following traffic stopped so I could recover my part that was in the middle of the road. So the question is, how is it held on? It seems the piece snaps into the two upright trim pieces on either side. Is/are there clips or whatever that hold it in place?? Thanks, Frank in sunny Eugene
