I have old style "period" chrome tripple gauges (Temp,Oil,Amps) mounted just under the dash in the middle.Thats where most blokes would mount the gauges in days gone by.
Mounting the gauges in the glovebox seems a bit silly to me.The gauges are there so you can tell how things are going in the engine bay.Closer they are to the driver the easier it is to tell.Way over in the glovebox makes it all so difficult.
The original ones wern't a gauge as such but just a warning light.
They are often referred to as "idiot" lights.
Basically, if your generator wasn't charging,engine was overheating or your oil pressure had dropped then the warning light would come on.
Any "idiot" should know to stop the car if the warning light come on.
