The German word for a tachometer is “drehzahlmesser”, and that is exactly what I have decided to put in the ’69 beetle.
To do that I have purchased a donor dashboard which I found on vwnettet.dk I have used the metal from around the speedometer and welded it into the middle of my own dash. Finally I have closed the old holes from the original switches for light, windshield wipers, sprinkler, and emergency light since these are going to be flip switches placed below where the ashtray used to sit.
Now I need to find a tacho from another car, so I can modify it to fit my beetle.
