Fenn Rudder wire stoppers

I am trying to buy the rudder wire stoppers Fenn uses behind the foot peddle to operate the rudder. Have attached two photos. Does anyone know where I can get them?

Try Fenn?

I know that medium duty wire barrier strips have at least ten of those in each one.
You can also get them in brass.

I assume you wil have to reswage (is that the right word) the cable to retrofit the wire stopper. Why don't you reswage in front of the pedals and run some spectra through the pedals. Most new boats do it this way these days. Will be cheaper and easier.
