Well if you have a stick shift….
My dad put one of those push/pull toga switches under the shifter boot.
You just had to feel around the ridges of the boot to lift it up or push it down.
If you look in the junk yard or auto store you could get one of the old "bright/dim switches that you had to step on to bright dim the light. Just put it in the floor behind the emergency brake. Just like it was original. They would never know the difference.
