I picked up the wedge for the instrument rib and bracket that Tim Conway had made for me. It fit perfectly and the canopy support arm nests right in the slot that was milled out. I drilled the large wedge in place with the canopy support arm bracket to the center rib. I clamped the canopy support arm in place to the canopy roll bar and then clamped the arm to the bracket, wedge and rib. I drilled pilot holes thru this combination and marked the position of the bolt hole at the top of the support arm and roll bar. These two pilot holes were then drilled up to size for AN3 bolts. All of the holes were deburred. I also primed the doubler on the opposite side of the center rib.
