Thank you for the responses.... Steve, I purchased one of the Sun, retro tachometers. Did the same thing that the older models I had did.

I love the look and accuracy of the old mechanical tachometers. I even have a couple. I do not have a cable drive distributor. Actually I do have one that's in my son's incomplete car. Never ran the dual point distributor style distributor. Will it work for racing applications up to 7000 RPM? I have a potential source for another one, and that would be my first choice, but I've been skeptical about the performance of the ignition. Help me to get a warm-and-fuzzy feeling; )
