Ok, a new question/new problem with tonneau cover....
I took a old 10mm wrench and grinded it down so it would fine in the slot. Found the nut(?) it fits on and for the next 1hr., my buddy and me tried to get the cover to lock. We could get the mechanism to lock but not with the tonneau cover down. I could not see any reason for the cover not to lock. Fit tight like it did when the hydraulics would lock it up. Finally said the hell with it, hopefully ever thing will be back to normal when the 2 cylinders get rebuilt and re-installed.
