Thanks a lot for the post and info! I appreciate it!
I didn't see your question until just now. Ford makes that cover in two versions. They make one that mounts inside of the bed rail and is flush with the top of the rail. The other one sits on top of the bed rails. I prefer the one that sits on top of the bed rails.
I've probably sold at least 50 of them over the years to customers of mine.
