Gauge Diameter

[zerfetzen]

I've been toying around with the idea of making a custom dash as I'm restoring the entire car.  If a gauge, say Auto Meter, has a diameter of 3 3/8", is that the diameter of the hole I cut out, or if not, how do you know that?  I'm trying to determine how many gauges I can fit

Hello zerfetzen! I did the same thing to my '70 Charger's dash. I used the Autometer guages too. I started by cutting the holes out by following the factory lines that are pinstripped silver. Then, using a dremel tool carefully cut the holes so the guages had a tight fit. I've included a link to my web site that shows a bunch of pictures of how I did it. Take your time, and you can get the same guages as factory, but with the dependibility of having new!  Take care! Jeff
