'67 Dart - No stop lights, turn signals on but don't flash

Mattax Thank you for the bulb information and the links.
I've taken the Front RH bulb out and cleaned up the ground strap back to the front panel, reassembled but no change.
The status now:
The earlier short has not shown up again (dome light still working).
All bulb filaments can be illuminated in one way or another, LH, RH, turn, park, stop, tail.
LH & RH turn signals not flashing, on constant, new flasher unit is on order; with flasher removed turn lamps can be flashed using a wire to short where the flasher unit should be.
4-way emergency flashers work in 3 places only, not working front RH, not working green arrow in instrument panel (RH hand turn signal illuminates all of those bulbs, front, rear & instrument; just doen't flash yet).

Waiting for new flasher unit.....
