64 Barracuda hazard switch

If you're after the original optional hazard flasher setup, it's going to be a "go fish" item. They don't turn up very often. The old-fashioned add-on hazard flasher kits are still available as Signal-Stat part number 127. Truck-Lite owns Signal-Stat, so any Truck-Lite jobber (most heavy duty truck supply houses) can order you a #127. It still comes with the old-fashioned transparent red illuminated pull knob. Installation instructions are here.
