Check out the JCR molle panels. They mount independent from the bed rails. Unfortunately, that would mean you'd have to buy new panels.

I just ordered mine and should be picking it up next week. Once it’s installed I’ll try and post pics.
Is your Access cover the Literider or Original? Can each mounting hardware be moved or are they set as is?
I’d contact Access directly. They have extra parts for each system to purchase. In my experience, I wasn’t able to switch from clamps to trail rail setup because I would’ve had to purchase each rail on both sides since the mounts were integrated into the rail - each unit was $130. Keep in mind...
