1969 Chevy Camaro Rocker Panel Moldings

I've built three Camaros in the last two years and replaced the lower rocker trim each time. The first two I used other makers product, but this time I bought the AMD units from CARiD. These went on without deforming like the others as they clip into place. I also noticed that the parts are stronger where the exposed sheet metal screw anchors the molding.
