I had mine made by a local shop, Instrument Sales and Service. They are a speedometer shop and they also make custom push-pull cables. I took my old huck-type brake cables to them, and they copied them using modern materials, and I put them on and they fit perfectly and are expected to last much longer. The whole thing cost me $80 and they had them done in three hours. The cables in question were unavailable from most of the vendors I asked.
