This evening, I installed the throttle quadrant for what I hope will be the last time. It looks like all the time I spent adjusting the cable lengths and quadrant arm throws has now paid off. The holes in the arms look like they are going to be perfectly aligned with the clevis forks, with a good spacing from the forward throw limits on the quadrant. The next step will be to insert the clevis pins and their cotter pins (which will undoubtedly be a challenge).
I also connected one of the Molex connectors behind the quadrant.
