This was much harder than the left side was. After flipping it over to get the other side, the holes would not align without a lot of persuation. I sure could have used another pair of hands at this point. I eventually got the center holes to align and I simply worked out from that point (up and down the center ribs (HS-707 and HS-708), then across the center spar (HS-702), up and down the HS-706 rib, and finally accross spar HS-603PP.
