I've been mulling this over for some time and considered sending my instrument cluster out to be restored but have decided that kind of money could be better used elsewhere. Like on gas this summer! All of my gauges seem to work "OK". No real major issues. I believe that replacing the voltage limiter with the solid state which is available from RT Eng. should clear up 95% of any issues. Cleaning and lubricating the mechanics should help considerably. My clock will be replaced with an OEM Tick Tock Tach. I have already replaced the circuit board to work with electronic ignition and tested the clock, which appears to be working. It wasn't supposed to be operational but hey, I'll take it! All of my bezels, except the instrument, are in excellent condition. I considered restoring the instrument bezel regardless of the missing corner but thought it would always be a bother to me. This is what you look at every time you get behind the wheel! I've since tracked down an intact bezel and will be restoring it. The one in the car will be my test mule.
