I'm probably missing something, but on page 34-6, how do you rivet the AN470AD4-5 and -7 at the top of the hinge frame? I can't get a bucking bar in there as it's blocked by the seat back brace, and I'm hesitant to use blind rivets here.
I was able to get my Tungsten bucking bar into one of the holes in the underside of the seat brace by sliding it towards the center of the fuse. Then slide it back toward the rivet once inside the brace, as I recall.
