1. Drilled out all 1/4" and 5/16" bolt holes in both wing trusses to remove excess powder coat. Broke 1/4" drill bit when drilling out powder coat. Drill bit bit hard and snapped in half. This only happened with a slow drill speed. I tried turning the bit faster and did not have this problem again. 2. Fit two of the truss attach points to the left truss. This is a slow process of drilling/reaming the four holes until you can get all four bolts in place. 3. Assembled the left truss atach point. The instructions omitted the part list drawing number from the instructions. It took me an hour to find the correct drawing to reference for this task.
