Did Delco Remy make 12 volt regulator without adjustment screws?
I'm with Jerry. I've never seen a Delco Remy without adjustment screws. And I've seen people get into a real mess trying to adjust them. As I said before, a good one generally lasts a long time. When I say a long time, I've seen some of them last 30 or more years. A substandard one might last a short while and a Chinese one might never work from the moment you unpack it. Good luck.
