I will be using a Gretz mount for the Garmin pitot tube. The Gretz kit was designed for the RV series but I just didn't use the backing plate provided, instead, fabricating one from .040” aluminum sheet, cloning what is on the RANS forum tech questions. This doubler will butt up against the outside edge of the fifth rib and the pitot lines will go outward from the tube then curve back to the root of the wing.
