When I looked around for this Westin part, I finally found it at Revain. This step of the replacement uses 7 plastic bolts to hold it in place. Don't bother buying replacement metal clips, just pry open the old broken step and use a 1/4" drill bit to drill out the old plastic stuck in the metal clips. The plastic shavings fall out of the bottom of the Westin Oval tubes, then just line up the pins, push them in and you're done.
