Installed the rudder per 8-18. I am having troubles with the bottom bearing cuz I need to back it out alot. I had adjusted the three bearings way back in the early days. Top: 51/64" Middle: 63/64" Bottom: 1 3/64". I removed the rudder and found that they where not adjusted properly so I reset the bearings and installed the rudder once again. Now it fits perfect without too much final adjustments. The coutherbalance gap is also perfect.
Lower bearing
Middle
Couterbalance distance from the Vertical Stab is good.
