Tuff Stuff7069FBULL6G Alternator (140 Amp Ford 1 Wire 6-Groove), Black

Originally was going to return it because manufacturer uses GM outer housing that wouldn't work with my belt tension adjuster. After talking with one of the techs, I found that they needed to use a slightly larger case than the 1 G Ford to make a 1 wire high output. Customer service was great and sent me a return label. They did all they could to satisfy me, so in the end I decided to keep it and modify my adjuster.
