I found that an aftermarket boost gauge will go easily in the stock spot. (Showing 9 pounds of vacuum at idle because of the cam. Volt gauge turned around so I can see the needle on 13 - 14 volts through the steering wheel when driving.) Used a hole drill for all the gauges. They fit so tight I didn't have to secure them from behind.)

Some SC owners manage to place other aftermarket gauges in the stock spots. I didn't have the patience to figure out how that's done as in maybe ditching the instrument circuit board?

It takes more work, but you can mount an aftermarket gauge so it almost looks factory. Check out my garage page for my 92 for more pictures.

There have been a couple threads where people have posted up doing a similar install as Kurt showed (including oil pressure and fuel gage I believe). I like the look/idea.

If someone who has done this could post up a "build"/tech how to on it that would be awesome. I'd love to do it as well, but am a little leary of tearing up parts to try it without some idea what I'm doing :rolleyes:
