Do you know what year or years: Grand am or Grand Prix these gauges would have come in as an extra cost option? Did the base model Grand Ams all come with full gauges except those cars all had a clock in the 1st circle, and then the tach was available to order at extra cost?

I remember seeing a few '73 or '74 and up Grand Prixs in the 1980s as used cars that had a big vacuum gauge in the first circle.

I think it said "fuel economy."
