Riveted the Wing ribs to the front and rear spars. I hate riveting AD4 rivets. I ended up turning my rivet gun up to about 60-70 PSI which helped set these beasts. Thankfully I was able to use the air riveter on the rear spar... not the front though. Bucked all of those... I probably drilled out about 20 rivets between both wings, mostly because of tagging the round head with a smily. glad thats over with.
