My voltage regulator went haywire today and the 911 tach in my 6 conversion took a hit (my atlernator is internally regulated)...it was a nice 74-77 tach that didn't need a tach adaptor to run with points and a MSD box. The P/N is 911-641-301-29. I'm told a tach from a 78-83 SC would also work...However, I'm not sure about that. Let me know what you have in your parts stash. Here is a pic

I don't have a tach but am looking for the same part #. It is my understanding that you need one for a MY '74-77 911. Haven't heard about the later SC though.
