Wow, what a pain. Tried to get my son to crawl in the back of the tail cone to run rudder cables but he couldn't get the spade on the cables through the snap bushings. Ended up crawling back there myself and was able to get it. But of course the first try ended up with the cables twisted and had to redo it. I think I was in and out of the tail a total of three times. Each time more awkward than the last.
Finally got them run all the way to the front and then installed the adel clamps in the rear and the adel clamps at the front tunnel exit.
10/22: fabricated the links and primed and then installed them. Drilled the holes in the nylon cable guides and then match drilled them to the tunnel ribs. Installed. When fully tightened, they are a bit too tight in the cables, so backed off a little. Need to play with that later.
No cotter pins installed yet, all of this needs to come apart later when I paint the interior.
