For years we've offered the Aeroforce Interceptor Scangauge to the 3800 community and recently we offered it for the G8 community as well. There haven't been a lot of options for mounting these so we decided to come up with something simple that will work for all G8's and not only for an Aeroforce Interceptor Scangauge but for any single gauge. These are available currently for pre-order and should ship by the end of the week.
INTENSE-Racing.com: INTENSE G8 Cubby Gauge Mount
Here are a few pics of the setup:
The mount is made of 16 gauge sheet metal and will be watercut for precision. Installation will be dead simple requiring only that you pull off the radio faceplate and attach it with two screws.
