speedometer halda hookup

#1 Post by Jeffrey Vogel »

I am trying to source the correct t-gear to attach a halda speedpilot to my 356 SC , don't have the speedo out of car at moment, does anyone know the thread size and pitch for this porsche ? seems that the halda t gear V14-N is a metric M 18 x 1.5
