1979 Bronco gauge

Hi everyone, I am looking where I could find this gauge, anyone have any idea of what it is or what it’s called

That is a vacuum gauge, it shows the economy/load of your engine. Not sure about finding a stock replacement, Ive actually never seen one of our trucks that had a factory vacuum gauge, but any aftermarket one should be a plug and play.
