Hi guys, I'm completely new to this forum and have the following question. Below my stereo system , my car has a cavity the exact same size as the stereo unit above it. Does anyone know if you can get a unit containing various gauges such as oil pressure, vacuum and voltage (Just as an example - does'nt have to be that exact combination) that are combined into such a size that would fit neatly into this space. I have scoured the net and cannot seem to find anything. I can't understand why gauge makers don't design their intruments around such a universal size. Can anyone help? It is for a Holden TS Astra 2000 Model. Thanks in advance.
