Long session. The pushrods had been attached and adjusted. Task was to install the bolts and bushings. I made the bushings and got all the hardware ready (an hour in itself). Getting them all on the bolt proved extremely difficult at first. Then I got a dental pick and used it to slide through the bracket and the parts. Once the fine piont of the pick went through, the thicker handle lined up all the parts and the bolt could slip through relatively easily.
Brain fart. I went to fit the flap brace and discovered I had already riveted some of the holes that went through the rib ends. Had to drill out four rivets. Fortunately I am an expert at that now.
