Installed the static ports without too much difficulty. The instructions call for a particular pulled rivet that you then remove the remnant mandrel and end up with a hollow hole in the wall. I used a C-clamp and socket to gently drive out the mandrel on the R side as I have an extreme allergy to using any kind of hammer on my airplane! The technique didn't work as well on the L because the mandrel stem I was trying to use a driver wouldn't stay centered so I held my breath and drilled it out with my trusty #52 drill bit. No problem. The picture is of the 1st port I installed.
