if you just put the white faced overlay in there it wont change the color. It just sits on top of the gauges now. As far as i know anyway.....

 

not sure...they used to only be on ebay...i guess they are doing pretty good to have a real site now...i was going to order my gauges from them but have decided to get them from speedhut.com since they have more choices and they can make a matching AC panel and other aux gauges in the future
