RE: Repairing Rudder Push Rod
One point to consider, the plastic clevis is probably a metric size, while the solder on end is most likely 2-56 threads. I woud suggest a metal clevis to match the threads. The kit plastic clevis will not screw onto the 2-56, the hole size is to small. If you do get the threads to bite and get it scrwed on, there is a good chance of splitting the body.
