Walker posted a good shot of the 'plastic hanger'. The pics I posted are aftermarket rocker armor. But you can also see the installation from start to finish by checking out the article. Here ya go, click the link.Okay, I think I understand now with Billjohn's picture. So Billjohn, is that what is actually behind the plastic covers, or is that some aftermarket part for what usually goes behind the plastic. Like a good replacement for a rusty piece? I guess I could go out in the garage and take a peek under the Sami to see if that's what's mounted undet the sills. Maybe tomorrow.
