i took a piece of abs plastic (1/8")that you can buy in 1ftx1ft squares (i got mine at canadian tire,but home depot or any stereo shop etc has them) i took out my vents and then traced the front side of the vent onto the plastic making the template a little bigger. then i trimmed the cutout to fit exactly to the vent opening using a small air sander(but a grinder or file will work) if your using 2 /16th gauges you need a 52mm hole saw bit to cut out the gauge holes(just measure the plastic length and hieght to get the center pionts for the drill bit) now put a piece of stereo backstrapping bent into a 90 degree angle and screw it into the center of the vent opening.there is a chunk of plastic around the vent opening to screw into. I used a 3/4" flathead screw. drill a hole thru the abs plastic to line up with the backstrapping and put a bolt thru with a nut on the back side(i used a longer screw with a tightening clip that you get with speakers) test fit everything as you go and paint if you like.
I hope this helps. Sorry for the long explanation but i've done about a dozen of these things now and i always find something easier or better about how to do them each time.
I'm working on a fiberglass version of this install for the center vents as well as driver's vent and passengers vent so the gauges will be angled towards the driver.
