I thought about doing that, but it involves modifying the back of the speaker cover, something I didn't want to do. I like the gauges on display, and on a road trip the volt meter saved my ass by warning me of a dying battery before the idiot light would have. It's easily reversible, like all my period mods.
In American, having coffee in your ride is more important that knowing your oil temperature, unless you are racing.
Is there space to install the gauges in a recessed way so stock wood speaker cover can fit over it?
If yes, Remove speaker cover to drive, and replace when parked or showing the car.
