I found a trick on accident. I installed some standard 2 1/16 gauges in my Jeep 1977 CJ5. I needed to make the hole in the plastic gauge face and the thin metal behind it.

I found an old cutting tool designed to cut the holes for doorknobs laying around the house and it turned out to be the EXACT size I needed.
I just put it on the drill and drilled the hole through the plastic and metal with it. The new gauge fits snug and looks great. It does take some patience to get through the metal, and the tool was pretty much destroyed, but at $2.00 for the tool, and seeing as it is a perfect fit, I figure it is worth it. I used the wood version, I'm sure a metal version would survive.

If anyone wants to see pics, I have them here:

eventually I will figure how to put them in my post.

Nice, where did U get the gauges & is the oil gauge electric or mechanical?

[dave123]

I got the gauge combo set from pet boys sunpro oil/temp/volt. $39.99. Oil is mechanical. If you go mechanical oil, you should really get a metal line, toss the plastic one it comes with in the trash (I had one melt once, big mess).
The fuel gauge is auto meter from Quadratec.

Looks good,. to bad it's "by accident"

That's just a hole saw for wood, whichis why it was destroyed cutting the metal. Lowes, Sears, Home Depot all have metal hole saws. They are a little more money, but they wont be destroyed and will cut through slightly thicker metal.
