I installed a 12-volt alternator in my '29 Tudor and would like to have a voltmeter gauge in the stock ammeter location. But, the stock ammeter hole in the dash plate is only about 1.5" in diameter while available voltmeters are 2 1/8". I found a digital voltmeter which is smaller than 1.5", which I can probably make fit, but I think an analog voltmeter (one with a needle) would look better. If anyone has done this, please inform me as to what gauge you bought, from where, and how you installed it. I think I could bore the dash plate out to fit the 2 1/8" gauge, but would prefer one that fits the stock dash plate. Thanks.
