    7127NC - Tuff Stuff Chrome Alternators is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from WORKS WELL, PROVIDES THE XTRA JUICE Alternator arrived, could not connect because I was not aware that an pigtail adapter was required to connect the new pigtail to the old wiring harness alternator pigtail, would have been helpful if JEGS would have made me aware of this need and would have been nice if JEGS carried the pigtail adapter. I had to shop the web to find the adapter!
