The 1970 assembly manual shows a 370408-S100 clip retaining the taillight harness to the taillight mounting studs. This is some sort of J clip. What are people using for this? Maybe just the usual J clip that is normally found on valve cover bolts to retain the engine feed harness? I don't see a source for this specific clip.
Oddly, the special flat style retaining nut is available, but the clip is not?
Car in question is a 11/22/69 Dearborn built Boss 302.
