Hey Don - -
Page 46-06 in the instructions cover the bolt installation. Calls for simple split lock washers. The picture is very clear. The issue at this point is how to ensure they stay put. Several of us have had a problem. Some of us have Loctited, 'blue', these bolts. Maybe by the time you are ready to install these, there will be a published solution. Just keep 46-06 in mind.
