70$ voltage regulator vs 20$ one, is it worth it?

...........just read about how these work and have rapidly moving parts (points).

but your parts look odd wrong dan, I'm looking at vr32b or vr32

Most of the newer replacement regulators will NOT HAVE "moving points" and in fact have been updated with a solid state unit, even though the original was "vibrating points"

Looks to me like Dan is AFU

The Echlin Vr32 appears to be the correct up through '69 regulator
