We run our 63 Plymouth in N/SS. It's a pretty realistic interpretation of the original cars. We try to keep it as visably close to the way they were as possible. One place we made an exception is with an MSD Ignition. We run a 6-AL with an MSD Distributor. The box is hidden-ish, but the Autometer Tach is a real eye sore. Is there a solution to running a vintage tach with the MSD?

I sent an old unit to "The Clock Doc", and lots of back and forth, and $300 later, it didn't work. We tried tach adapters and other electronics to see if we could find a solution, but no-go. Any ideas?
