Measuring 11 25/32" from the body of the flap handle to the center of the CM-4M rod-end bearing.
Found it easier to slide a bolt through the CM-4M rod-end bearing and place a line on a piece of paper so the bolt could be visually kept square for the measurement.
Completed pushrod/flap handle assembly. A piece of paper with a line drawn on it was used as an aid to keep the CM-4M rod-end bearing square while obtaining the proper length measurement.
After the correct measurement was obtained, the parts were secured with jam nuts and a drop of blue Loctite.
