TPI Conversion

I am completing the conversion of my 73 from naturally aspirated to TPI. The original distributor has a mechanical connection for the tach but of course the new distributor does not. What is the easiest way to convert to an electronic tach and where can I locate the parts?

Just thinking out loud... Im pretty sure 75 and up use an electric tachometer, so your path of least resistance is to pirate a tachometer from something like a 75-77.

When I converted my 71 El Camino to a TPI I sent my tach to D and M restoration in S.C. and had them do the conversion.
