Had two clips break on the back side. Thanks to Dave, was able to find the replacements. Those GM parts just need a bit of trimming to be flush but otherwise have exact same dimensions. One thing that wasn't obvious to me right away is that putting the clips on the skirt and sliding the whole thing onto the rocker is the correct way. I tried putting the clips into the rocker and sliding the skirt on to them at first - impossible. On the back of the skirt, I had sticky tape that came off with Goo-Gone easily. Epoxy glue Ford uses on the front, however, had to be sliced off carefully with a box knife. I used 3M gray, outdoor tape on both ends. 3 weeks later - no issues.
