Replacement Tachometer Drive Cable

[laingjs]

Does anyone know where I can find a replacement for the 12" tachometer extension drive cable that Van's used to sell? It had the Clark Brothers tachometer drive fitting at one end for Lycoming engines and a square drive at the other end to fit into the tachometer transducer. The shortest I've found from various sources online is 22". thanks

Last time I needed one, which was a long time ago, I went to a local speedometer shop with the old cable and jacket. They built one up for me.
