This is where mine are and it's headache central. Not to install but they just are really useless there. That's why I put my boost gauge on the pillar. I do want them setting just above the A/C vent. I also like this look. To get his gauges to fit, only two would work best. I have a set my brother bought me that are 2" and they fit great. I used MDF to fill the entire hole then drew out the area of spacing side to side and top to bottom. Then cut out holes and the rest is self explainitory Not really that bad if you really need them. You can see them by linking the sig1991S13 wrote:That would look nice, but have you ever thought about putting them in the pocket under the radio? Don't know if they will fit, but that might look good too.
