Read SB about co-pilot stick attachment. Searched for and found multiple pins to use in place of the SB specified AN3-13A bolt and added the information to the maintenance manual to consider in the future since I won't know for sure what might fit. Removed and drilled the co-pilot stick for the AN3-13A bolt and reinstalled it. Used torque seal on the three nuts in the controls that are torqued to final spec and shouldn't have to be removed later. Decided to replace the bushing in the two sticks so they will be captured by the yoke and kept from rotating. Placed the bushings in my Van's cart since I couldn't find a similar part at Aircraft Spruce or McMaster Carr. Updated the Trim, Autopilot, Flaps and control information in the maintenance manual. Drilled and deburred the holes in the transponder and COM antenna doublers. Match drilled the transponder antenna doubler to the fuselage. Dimpled the transponder antenna doubler and the holes in the fuselage skin. Still need to drill holes from the doubler to the seat ribs.
