YEP! I told you I live "out there"!! I'd guess that you need the "adjustable" bolt in the third or middle hole on both pairs of brackets. Remember to keep the amount of strap material in the reel of the ratchet to a minimum (pull all excess strap through the reel before ratcheting). If you don't, you will loose leverage on the handle of the ratchet and the excess material can build up and interfere with the "catch" in the ratchet stop.
Going to work now and will be back at midnight!!!
