I had it professionally rebuilt and calibrated by a very good gauge guy. He installed a solid state voltage limiter when he rebuilt the cluster. Temp sending unit in the cylinder head is good too - an original Chrysler unit. Wiring all good.
Unless you've verified it with a temperature gun, you don't know whether the gauge is accurate. "NEW" or "PROFESSIONALLY REBUILT" still don't mean "GOOD" unless they've been verified.
