I finished the construction of the right main spar. I decided to rivet the outboard vertical stiffener angle(SNX-W11-11) instead of just bolting it. I also attached the right-hand tie down fitting(SNX-W11-10R). This required bolting into tight-fit holes. I had to ream the two outer holes to 0.1865" and the middle hole to 0.1870". The middle hole was still quite tight but I was able to tap it in with a hammer.
Next, I need to fully inspect the spar to find bad rivets that need to be replaced.
