Put a new turn signal switch in because horn contact broke off. Turn signals worked for a few minutes then quit. Have power to orange wire at flasher. No power to blue wire at signal harness connector. Also brake light switch moves enough to turn brake lights on and off. Dont know if related or seperate problem. If you leave turn signal on you will get a flash or two every now and then. Then it will stop.

Wiggle the hazard light switch in and out a bit. When things go weird on my 67 that usually fixes it.

Get a helper. Disconnect the turn signal flasher. Have your helper sit in the driver's seat with their foot on the brake.... the brake lights work, right? And you said you have power at the flasher?

Have your helper select the LEFT turn signal. The left brake light should go out. Have them select the RIGHT turn signal. The right brake light should go out. If one or the other or both brake lights do NOT go out then you have a problem with the turn signal switch. If they go out as indicated replace the flasher.

What was the results of the test I suggested?
Had to order and put in a new brake light switch to get light to work consistently. With someone stepping on the brake the brake lights go out when you hit that turn signal.

Forgot to unhook the flasher though. Will try it again in the morning.

With flasher unhooked and someone stepping on brake pedal. Brake light goes out when you flip turn signal switch. Thing is if you leave key on and turn signal on you will occasionally get two, three or four flashes then it stops. Was thinking about ignition switch since it needs to be on for signals to work.
