Finish-drilled four #12 holes in vertical tabs and cockpit rails and bolted down. Starting at the back and working forward, match-drilled six #12 holes on each side of weldment through cockpit rails and longerons, bolting each hole as it was drilled to pull the part carefully into shape. One weld cracked between gusset plates during tightening; should not be an issue as parts are held in compression. Will call Van's and ask if rewelding will be needed.
