Access lorado and rails question

First, I am sure I'm posting this in the wrong section but I couldn't find a forum group that made more sense.. Anyway- here it goes:

I just installed the acess lorado cover for my 09 shortbed. I am fairly happy but now it seems I can't use the adjustable D rings that came with the truck ( the ones that install on on the side rails. I really need this capability. What alternatives are there for me? Has anyone bought another maker of d rings that will work with the setup I have? I can slide a ring onto the rail but tightening it is difficult if not impossible...

Another concern I have is I might want to use a cargo divider in the future.. I wonder if I'll have problems a this too?

 

I also installed the Larado cover on my long bed '09 Tacoma. If I knew that the side D rings would not work I would have purchased the regular Access cover. The front D-rings will work not the sides. I installed an aftermarket set of tie downs from Northern Tool. I will post a picture. They are not adjustable but I mounted them 1/2 way and this works great tying down my dirt bikes.
