Match drilled the F-721A left and right canopy deck. Then countersunk the F-718 Longerons, dimpled the canopy decks, etc. It's obvious that once these are installed it gets real tight for a bucking bar where the two join together so it made sense to install the 2 rivets that join these pieces together on the bench. Then I clecoed them to the longerons as a unit without problem. I then started shooting rivets and was able to get to most areas with a small tungsten bucking bar, but I ran out of AN426AD3-5 rivets.

I can't imagine why I don't have more of these. Vans gives you tons of rivets, and this is the first time I've ever ran out of a specific size. I spent about an hour tossing the shop, thinking that there must be another bag that I had overlooked, but no joy. I called Airparts thinking I would just run across town for more, but they don't have them in stock in ICT and are getting them from the Florida store, allegedly to be here on Monday.

At some point, I realized I had misread the slider canopy detail on drawing 25. Turns out there are 3 AN426AD4 rivets aft of the seatback crossbar common to the F-718 longeron and the F-757 plate. I drilled these holes and used a chip chaser to clean out burrs between the layers, and was able to reach them all with a squeezer.
