Excessive ballast resistor resistance?

I just for fun looked up a 70 Plymouth RR 383 at O'Reallys and they show an (BWD) RU-6, but I cannot find a listed spec for resistance.

NAPA shows two, both incorrect, and both way over 1 ohm, 1 is 1.85. Christ O'mighty, what ever HAPPENED to parts in this country??
