1970 Dodge Dart Cluster and Gauges

What I see beyond the missing gauge voltage limiter that has been mentioned above... the speedometer needle should rest at '0'. So something is wrong with it. The amp gauge needle should be exactly centered. Something wrong there too. There are several service vendors to send it to.
Speedometer is the most complicated/precise instrument of the group so it will be the major cost factor. Good used available? Don't bet on it. Good luck
