The upper bolts on the main gear weldment had three holes that were time comsuming to fit AN3 and AN4 bolts through. Just like the left side, you have to blindly tip washers onto the bolts, and blindly tip nuts onto those bolts. I had to extend the reach of the reamer for the AN3 bolt mentioned earlier because the drill trigger hit the spar before the bit reamed all the way through. So I added two washers behind the reamer and it barely screwed itself onto the angle drill. However, that worked and the reamer reached all the way through. I'll continue installing and torquing all the way across the spar.
How you can extend the reamer length. The trigger prevented full penetration of the reamer.
Need to install the F699 on the copilot floor next.
