Clecoed VS-704 Root Rib, VS-705 Nose Rib, VS - 706 Tip Rib and VS-707 rib to VS -702 Front Spar. Riveted with rivets called out in the drawings. Middle rivet that attaches nose rib and root rib had to be raplaced because I used too short of a rivet and didn't have proper dimentions for the shop head.
