The 4 way flasher on my 74 Road Runner was clipped to the frame of the brake/clutch pedal support up under the dash. Not easy to get to when you do know where it is located! It is a square flasher can and has a green slip on clip that hooks over the edge of the brake/clutch pedal support up high under the dash behind the instrument cluster. The turn signal flasher was located just under the lip of the dash between the ash tray and the glove box.
