Don't mean to hijack the thread, but I'm New to the forum, and am looking for the name to a piece of plastic I need to replace. I have a 2013 Expedition. On the front drivers side rocker panel there is a piece of plastic that is coming off. It's about a foot long and there are four to five holes on the panel where this fits into. If you don't mind, what is the name of that piece of plastic? Thanks for any help.
