When I built the wings I fitted the standard Vans pitot but left the bottom skins un-riveted so that I could still run the wiring and maybe fit an autopilot servo, Im glad I did because when I chose the Dynon efis, of course it has its own pitot with built in angle of attack. I chose the Gretz mount and fitted it outboard of the rib just outboard of the most outer inspection hole.
Took the wings out of storage
I made an 032" angle and riveted it to the rib and doubler
