To start, the hole in the rib needed to be enlarged to 1/4" to accommodate the rod end bearing. From there, I could cleco the rib doubler in place and match drill the 1/4" hole into the doubler.
To drill for the platenut itself I took an AN4 bolt and screwed it into the platenute to hold it in place. I held the platenut as steady as I could to match drill the rib.

| The platenut ended up being slightly askew, but it'll be hidden well and it definitely won't bring the airplane down. |
Clecoing the one hole, I match drilled the other into the rib.
From there I removed the platenut and clecoed the rib doubler back on so I could match drill the new hole into it.
Finally, the hole I had just drilled into the doubler needed to be machine countersunk on the inboard side. There will be a flush rivet here to allow adequate clearance for the pushrod to glide over this area.

| An AN426AD3-6 in place that will be long enough to join the doubler plate and the platenut to the rib. |
Rinse and repeat for the left one. Easy enough!
