I used my squeezer to set most of the rivets joining the top web to the top flange and top of the seat back. I didn't want to wait for help to buck the remaining rivets so I drilled a few 3/16" holes in a heavy block of steel to hold a die. Then I just positioned the die/block under the seat back and used a back rivet set to buck them. They all worked out well but one, which I drilled out and replaced. Then it was back into the painting room for a cleaning and a final coat of SW988 to cover the new rivets.
