Chris primed the cowl latches and floating panel for me. I riveted the rudder cable fairlead in place near the tail. Bill helped me and we installed the last four rivets in the windsheild side strips. I tested the strobe and replaced all 18 externally visable mounting screws with new SS or AL. hardware. I installed the three rivets in the middle of the seat pan that had been omitted. Removed the left side spar spacers and rusty hardware, cleaned and inspected both spars. Reinstalled 3 of the four spacers with new bolts. Left rear spar not done due to waiting for bolts to be delivered.
