How many are using the factory amp meter

I have a 73 duster 340 car with factory AC. AC is not hooked up and I have no other add-ons. I would like to keep the factory amp meter hooked up in my dash but some people are suggesting that I eliminate the amp meter in the dash because it's a fire hazard. I had the complete dash out of the car to redo it and I Will never do it again,it's a lot of work. I had no trouble with the amp meter before and would like to know everyone's input on what to do. I like to keep my car looking original but if needed I can add an aftermarket amp meter.
