the way i do the upper mount is to install it with one screw.then tighten it a little.looking for the second hole.then insert the tool into the second hole lining it up with the slot.then install the second screw making sure it catches both sides on the rectangle hole.also dont want to tighten them real tight.it will calapse the bracket.once you have the fit right.i then back out each screw one at a time so they dont move.apply blue lock tite to the screws.re tighten them.light pressure is all that is needed on these.this info is in the instructions for all that have not installed them yet.
