Update post: I sent my gauge cluster to Redline Gauge Works in Santa Clarita, Ca. Spoke with Shannon ( he was great). They did a Tach movement replace with modern step motor. This required the addition of a 12v power wire. They also did a quartz clock movement conversion as well. My gauges were in great condition so no cosmetic work was necessary. Installed this weekend. Gauges work great!!! Tach is rock solid!!! Pretty quick turnaround and the customer service was great. They always pick up the phone and answer all questions. Thanks RamAir for the recommendation!!!

What is involved in upgrading a '71 tach for an MSD pro-billet distributor that doesn't use an external ignition box? My tach died a couple days after putting an MSD in. So -- is the upgrade replacing the printed dash circuit? Will the aftermarket one made for '70-'71's work, or is another one required?
BTW I called Redline about a speedo noise and they were very helpful. I'm driving my tach over to them once I know what other parts I should bring to fix it.
