You know when you finish something and its not quite 100% you have two choices; leave as is and remember that its not right and should be changed or take it out and re-do it. After finishing the installation of the mast I was not happy with it. I just did not like the end result. Sooooo, I ordered another, pulled the first one out and installed the new one. This one I like. It is straight, well supported with appropriate rivet holes. After finishing the new install I bolted the bell crank for the aileron on that wing in place. If you look at image three you can see a small bracket with three holes in it. That is now in place to hold the pitot tube, AOA tube and coax cable from rubbing against the bell crank.
