There are only two attach points for the rudder but because of the need to insert washers around the rod end bearings, it's a major pain in the neck. But they got inserted. The instructions I have call for the elastic locking 365 nuts. But the new instructions call for an -03 metal locking nut, which I used. My guess is this may have to come off at some point before I attach the cables so I haven't torqued things down. I'm sending out my torque wrenches for calibration.
