I found some locking rivet nuts at McMaster-Carr that might work. Just wondering if you can tip me to what you found since it seems to be working well for you.

Michael, the nut slide inside the u shaped track of the 80/20 and is formed to lock in place when it is tightened. I'll have to find the picture of it to show you. Give me some time.
