Makes dual and triples gauge pods for our cars. Very goo dquality. Thanks to Wyatt for pointing me to these. I have one with Oil Temp, Oil Pressure, Voltmeter from Autometer
Since our cars don't come with one I definately recommend an oil pressure gauge, one of the best gauges to point out a problem before it gets bad. Since our coolant temp gauge isn't that detailed as far as what temp you are running you may want that. I went with oil temp since I did have at least some form of coolant temp gauge. A ammeter would be a better bet thaqn a voltmeter to point out electrical problems to come.
