Drilled-out the 2 Cherry Max rivets that did not set properly from the left stiffener angles. I tried 2 new rivet pullers without success. Finally, decided to use AN470-4-6 solid rivets which should have the same structural strength, if not better. Drilled-out 1 Cherry Max rivet from the right side and replaced it. Removed the F-1204V Drill Template from the right side and bolted it to the left side of the Center Section Assembly. Match-drilled #30 holes and final-drilled to ΒΌ in the left side (through the F-1204 Center Section, Outboard Wear Plate and Outboard Doubler Plate).
