Dash Gauge Circuit Board

Std cluster ? Are the 72-76 clusters the same as earlier Valiants and Darts ?

Please elaborate .
70 was the change yr

although my 70 Dart was a 69 dash down from the factory

It appears that Ma Mopar
Had the 69's on hand that day

Interestingly, I have a non AC car with factory AC holes in the firewall, equipped with a heater only
