I'll go with that. I unscrewed my old regulator, screwed the new one on, hooked up the wires and started it up. I was pleased at how smooth it worked until in a week or two when it started overcharging and boiled the battery, blew out light bulbs and made a mess under the hood.. Those sheet metal screws that attach it to the firewall don't grip much after 50 years and being removed 3 or 4 times.
