Taped rivets into place on right spar doubler. Was short one 426-11 rivet, so cut one -22 rivet to size. Placed spacers on rivets, found bars 1, 2, & 4 would not go easily on the last 1/8." Tried to place spar on rivets with flange strips 606B & 606A in place. Spar holes for spacers 1, 2, & 4 did not all completely line up.
