Lets install the elevator push tube. Fun. You need to adjust the elevator push tube length so that the hole in the bell crank mounting rib is in alignment with the bolt hole on the bottom on the bell crank. Easy, install the push tube, insert a long bolt in the bell crank bottom hole and adjust the length of the push tube so that the bolt is centered in the support rib hole.
It was fun moving the elevator up and down by moving the push tube.
