I wanted the angle for the side console to be flush with the rear bulkhead where it attaches. So I fabricated a bracket to attach to the rear part of the bulkhead. I made the bracket and after some adjustments I clecoed the bracket in place and drilled a hole through the angle and the bracket. Next I located, drilled and riveted a nutplate for a #8 screw on the bracket.
Will locate the bracket in place after attaching the angle to the throttle quadrant.
