I plan to use the Van's mount in its standard location on the right side. Installation was problematic with pop rivets due to head size of rivet gun for top rivets, causing a gap under the head of the rivet, and the angle for installing the bottom rivets.
My solution was to use #6 screws and nuts for the bottom holes and an aluminum washer under the head of the pop rivets on the top holes so the gun head could reach and achieve proper squeeze.
