I decided to just get the Silver Metal Flake with no special custom work done. I also ordered the IntelliGlow Needles. I will write up a install once I get everything.
I have installed the Gauges before on my old s13 and it was tedious but worthwhile. For the $ they are excellent pieces.
Here is a picture of them installed on the old 91 240sx. Notice I broke the little black cover of the Fuel needle while trying to take the needles off.
