For this aircraft, the measured the length of the linkage that connects the rudder cables to the rudder pedals is 1 - 3/4" for hole centers. Fabricated the parts from 4130 1/2" flat steel supplied with the kit. Deburred, then primed the parts. Installed them according to the instructions on plan page 37. That completes the control surface rigging, and now that the rudder pedals are operational, so are the brakes which will be needed once the propeller is installed and tested.

Just had to take another shot of the whole aircraft -- too cool!
