Clecoed the F833E Seatback top panel to the F833F Seatback top web, and squeezed all the rivets except 1 at each end. Clecoed the F833C1 top flange to the F833F web and squeezed all but 5 rivets that couldn’t be reached with the squeezer. Sorta dreaded shooting and bucking these because the skins are pretty thin. The first 4 went very smoothly—probably got over confident at how easy this was going. So, on the 5th rivet, the bar slipped and put a slight ding in the web. Not a big deal since it will be covered by the seatback cushion—still, I wanted perfection! Next, I clecoed the F833B-L&R sides to the F833A seatback. Shot and bucked all the rivets on one side—decided to call it a night while I was still ahead. Will take up the gun and bar tomorrow and hopefully finish the rear seatback.
