Today I made up the pushrod that connects the two throttles. After it was fabricated, I installed and removed it many times as I expanded the holes in the fuselage to allow the throttles to move without the rod contacting the structure. I decided I was not going to use the standard 'ball' type knob on the rear seat throttle, instead electing to make one that is similar to the front seat throttle. I have a small but very handy lathe, made the job easy!
