I received the tach filter today and installed it. It turns out that I did not need one since the tach worked before the install but not once the filter was installed. So I removed the filter and hooked the wires back up as before and it works OK again. I guess I just had a lazy tach to begin with. It seems to be working more accuratley as the days go by. So if anyone needs a filter for an early tach that is not currently working on an electronic ignition, I have the non-OEM looking version (that you can hide) that I will sell you for what I paid for it ($22 plus shipping).
