No instrument lights?

For some strange reason my dash lights quit working, bulbs are good, I tested them. The oil, alt, and turn signal indicators all work fine. I twisted the headlight switch so it's not that I have them dimmed, they just quit.

Any thoughts?

Those main harness connectors at the firewall caused a bit of grief with my 64, they get pretty corroded. Might try those.

Thoughts? Yep. Sounds like an electrical problem.

Sounds like the light switch is telling you it's needing replacing.
I'd say.

Have you checked the lead at the cluster or switch to make sure the switch is sending power for the dash lights?

The rheostat in the switch might be worn out....

Do the lights at your heater control unit work?

No lights at the heater controls on a 67.

Instead of using Kentucky windage, how about referring to a wiring diagram?

It was the two amp fuse, pulled it, cleaned up the terminals and put it back in. Working now.
