            it worked

            took a couple of hours to put in, and it was a PIA to do. However once I got the Alternator out it was simple and cheaper than a new alternator. Do not believe the youtube videos on how easy it is if you have a Mach 1. However if it every goes out I would replace it again myself. 2003 Mach 1

            Cured my charging issue.

            This issue was hard to pinpoint. Sometimes the alternator would charge and sometimes it wouldn't. My battery was 6 years old, so I replaced it first. Was still getting erratic charging. I decided to give this regulator kit a shot. Cured the issue. Three weeks of daily driving and I'm getting a steady 14.3 volts.

            PAPerformance performs

            My lights were flickering on my '99 Cobra and the voltage would go above 15V. The PAPerformance voltage regulator and brushes installed perfectly. I did not install the bearings (yet) since my alternator is still quiet. My lights are no longer flickering and the voltage is holding between 14.0 - 14.6V, like it should. Much cheaper than buying a new alternator.
