Before I riveted anything I made sure to dimple the aileron bracket doublers and the holes in the spar flanges that any of the spar doublers would be covering. I maybe could have dimpled these holes later but it would have been difficult with the doublers in the way.
About the only things that I have left to attach to the rear spars are the aileron brackets and the aileron and flap gap braces. Those will come later once I'm done with the rest of the main wing structures, so for now I'm calling the rear spars done!
It's time to move on to everyone's absolute, undisputed favorite part of the wing kit, the wing ribs!
