Tach mounting

Back in the very early '70s I mounted a tach in my '69 340 Swinger using the driver-side visor mounting bracket at the upper left corner of the windshield. It was a great location for the tach because it was easy to see without moving your eyes completely away from the road. I ran the wiring down inside the A-pillar cover. It was also a bit intimidating to others, especially when it was lit at night.
The only one who didn't like it was a California Highway Patrol officer who told me it blocked my vision (it didn't) and provided me with a "fix it" ticket.
I simply wired in a two-piece wiring connector plug, took the tach down and stashed it in the glovebox, and tucked the plug up on top of the visor. I drove to the local CHP station and got the "fix-it" ticket cleared. Then drove about a block away, took the tach out of the glovebox, plugged it in and mounted it back up on the visor mount.
I never got hassled over it again.

On my current '69 Dart project the Speedhut shift-light tach is going in the Rocky Mountain Dashes panel I bought years ago.
