laid out, cut and drilled the plastic fairlead material, and riveted it to the angle. Installed the angle and fairlead to the rear of the seatback. The three rivets on the top were accessible from the front side and were easy. The three on the bottom half had to be drilled from behind, so I crawled through the bottom hatch into the fuselage cone and drilled, deburred, and riveted it in place - not fun, but I don't have to do that again! :-)
