Reassembled the L angle stiffeners onto wing ribs #1 - #4 and riveted them with A4 rivets. One of the rivet heads looks funny before I pulled it (sort of like that shriveled peanut you find occasionally when you're shelling them) and after I pulled it, it looked even worse. It was no problem to drill it out and re-rivet the hole.
It's always a good day when you get to rivet something!
All 8 ribs reassembled with rivets in place
Rib #2R all finished with the other finished ribs in the background.
Ribs #1L - #4L back up in the garage next to the left wing main spar.
