I got a Safeair pitot mast from Avery. It is a thing of beauty!. The instructions and template were also excellent, which made the installation process a breeze! This was done before the final installation of the lower skin. I then drilled the Dynon heated pitot probe to the mast, and tapped it to 6/32". I also purchased the Safeair 'Skyview' plumbing kit, which was of equal quality to the other components.
