I have a 1967 Chevy Impala and I'm trying to replace the fuel gauge on my dashboard and figures that they don't make 5" Fuel Gauges anymore(Impalas has big dashboard gauges)
The closet thing I found is a bunch of different models of Quad Gauges that have a fuel gauge on them along with other gauges:

Would this be compatible for my car? and all the other different models from AutoMeter.

 

You will need to replace the fuel sending unit to match the guage, also is it electric for the oil, and water temp? Depening on what you want with the Impala, i.e. keep it original or don't care, would dictate what you do with it. There are still salvage or aftermarket parts for replacement.
