Installed W20-01R Right Wing Doubler. Made a spacer from plexiglass to mark the gap. Allowed extra space in the gap for Vans wing gap seal. Clecoed the doubler to the wing offset outboard by 1/2 inch. Used the spacer to mark a trim line on the doubler. Used snips to trim the doubler. Clecoed the doubler in the proper location. Installed the Vans wing gap seal to be sure the gap was OK. Installed the rivets holding the doubler to the wing.
