Has anyone done this? I got Defi gauges in Boost, Pressure, and Temperature and will mount them on the A-Pillar and I think it would be neat to put the AEM UEGO Widenand Gauge in it as I already put in a blue LED in the cubby hole. Don`t I need a bracket for it too? If so, where can I get it? Any comments is greatly appreciated.

 

Cubby hole? You mean that pocket down there in front of the stereo where the cigaret lighter is?
I think garage 1217 makes custom carbon fiber cutouts for that with gauge mounts.
Other then that, you should be able to get a generic gauge cup and mount that in there.
