Well finally a win.I did the 3 g upgrade years ago,got my alt for 20 something bucks at pic a part.it went out in about 6 years,so got another this time it was 30 bucks.I looked on Amazon and ordered a brand new one for a Ford truck with 5.0 ,of course it wouldn't fit .I called to sent it back and they didn't want it.they did refund me.I took it apart and just switched the front half,put the new bearing in and my pulley.Win Win
