I installed the recommended #6-32 button head patch screws to secure the pitot tube to the mast and then installed the 37 degree JIC fittings on the aluminum pitot tubes. I reconfigured the tube bends so that I could remove the assembly in the future if need be. I then installed hose barbs for the soft tubing supplied for the pitot / AOA lines, routed and tie-wrapped.
After looking at photo #3 I realized that my fitting locations are going to interfere with the aileron pushrod. I'll have to re-group and make a new configuration.
