Need help with small side skirt rails
 

Hi guys I need some help locating some small side skirt install rails. Any pdf or the template would help a lot. Im also in search for the rail itself. If anyone can get me measurements or have any extra piece laying around I'm more then willing to pay for it and shipping. I will reproduce the piece in aluminum for my side skirt install. Seems the hardware is no longer available.

A lot of junk yards won't sell them separately. Searching did not yield any useful information.
