Here is a view of the pilot's side installation of the aileron push tube, bracket and bell crank for a cut down keel installation. The instructions were a little confusion, but I found a picture of an installation and it helped a lot. When you see it laid out like this it is pretty simple. Make sure you trial fit everything in place before you permanently mount anything. Clamp everything in place as you go so that it doesn't shift. If one part changes, the relationship of everything else changes.
Clamp the bracket in place first, centering the torque tube in the hole in the wing root. Then, set up a 90 degree approach angle with the push tube to the bell crank. Fabricate the strap to hold the push tube and trial mount it. Then attach the pull tube to the strap and trial fit again. If you are a little off on the 90 degree approach angle, you can adjust it by moving the bracket a little fore and aft, the strap fore and aft, or even the bracket inboard and outboard.
Moving each a little will allow you to get it just so. Once you do, start drilling and mounting permanently.

Here is the copilot's side. I got 2 1/2 inches up and down travel at the trailing edge of each aileron. I also got a lot of skinned knuckles. This is one of those deals where you have to reach up and around corners through lots of sharp and pointy stuff. Again, this will teach you patience (and refresh your repertoire of profanity).
