I got mine from a different company that sells them prepainted. Getting everything up through the dash to the a-pillar was interesting, but not impossible. These pillars are actually covers, although after I installed mine I saw where someone modified it a bit to make it replace the old pillar. This would save a bunch of room, and make it easier.
I mounted my pyro preturbo. I feel it gives a more acurate reading of what is actually happening in the engine.
As my signature states, I went with Di-Pricol gauges. Easy to read, but IMHO they are friggin' ugly at night. Orange and green? Who came up with that combination? I would have gone with the white face, but I can't stand chrome. Overall though, I was very happy with my choices.
