[NOT A TA]

Use some 80 grit paper to sand the posterboard till each gauge fits into the hole. Keep in mind that the housing of each Autometer gauge is tapered a little from front to back so just because you can fit the back of the gauge into the hole you'll still have to widen the hole till you can slide the gauge housing all the way in to the hole until the gauge trim ring contacts the posterboard. Cut out the holes for the AC vent and lighter opening. The lighter opening needs to be oversized a little to allow variances when the final panel is installed. The trim ring for the lighter will cover gaps.

Once you've got the openings finished lay the posterboard onto the plastic panel and tape into place. Mark all openings with a grease pencil and cut openings with a Dremel tool keeping in mind not to open the holes up to much. You will sand the plastic to fit after cutting with the tool. I use something round to be sure I don't end up with egg shaped holes.
