I got the top rail secured finally and got to hanging door panels. I've got the first one set on its pivot and have the top hinge in place. I'm trying to hang the second panel, but the holes are not lining up with the 'hinge'. It turns out you need to back off the adjuster (on the very bottom of the 'hinge'.) then install the mounting screws and then run the adjuster back up to level up the door panel.
