Shot primer on the F8103 spacers, lifter plates and cable release plate. After the primer dried, I riveted them together—used a -12 rivet. Plans called for a -11, but that appeared to be just a bit short. Drilled a hole in the left WD820 brake pedal, then installed it to the rudder pedals and the brake master cylinder. Clamped both brake pedals together. I used a long AN3 bolt thru the left brake pedal, left master cylinder and right master cylinder to verify to position of the hole to be drilled in the right brake pedal. This made both brake pedals sit evenly when the rudder pedals were neutral.
