I have taken a bunch more pictures for you. The top mount on my rudder is in good shape. I have included a bolt and what I think is the proper bushing for the top mount. After taking off the rudder to treat some corrosion on the bell crank, we discovered a torn piece just above the bell crank that we could have repaired with a doubler. (sp) After finding a good rudder, (I swear it looked like NOS), we decided to install and paint the new rudder rather than repair the old one. I truly hope this works out for you. I believe the "E" model is fairly rare and we need to keep them all flying.
