So far I have determined the headlight switch is the culprit for the dash lights (swapped with a good one from my 67), still working on the turn signals. What I mean by halogen is just non-LED. Not sure of the correct term.

Usually if your getting the hyper flash with the blinker bulbs, one of the bulbs is bad. If you swap out all the bulbs and your still getting the hyper flash, then on of the connectors for the lights is bad.
I had that on my truck when I first got it. I changed out all the bulbs, but I ended up changing out the connections for the marker lights in the grille, and that fixed it. Someone had poorly spliced them in, plus the connectors themselves just looked bad. Like they had gotten pretty hot at one time or another.

I will check and post my results. Thank you!

Your welcome, and good luck. Electric issues can be a pain chasing down. I know a little about chasing down issues. I worked in the repair dept at an auto factory for years. Bad grounds, cut or pinched wires were the bulk of the causes.

Good find on the headlight switch. I am a big fan of 'known good parts' as a troubleshooting technique.

It was a lot simpler before halogen and LED muddled the terminology waters. As long as you had the proper number bulb, it just worked. I was worried that your customer had tried to fit halogen(normally pre-LED headlight type bulbs) in the turn signal spots as some kind of super bright custom job. That could cause all sorts of issues with standard flasher cans.

Does the emergency flasher switch make all four corners flash? I use that as a quick check for the turn bulb filaments and connections.

Yes, the emergency light makes all the proper spots flash, honestly Im curious if I am having an issue with one of the flashers on the fuse block. SOMETIMES when starting a turn signal, or 4-ways, they will blink the appropriate for 1.5 flashes, then go fast.
