I was given a used Kyosho plane with a split elevator.
They were connected with a "U" shaped piece of music wire.
On each half there was a plastic piece bolted on like a control horn.
On this horn was a round horizontal shaft the music wire fit into snugly.
I need to replace these plastic pieces.
I am having trouble searching for them since I don't know what they are called.

I apologize if I am not describing them well.
I also can't get pictures as they were badly broken.

I hope someone here can help.
Thanks,
