I agree I should have known better. I've swapped this particular alternator twice before and have always swapped it. I was plenty upset about the 3 month alternator failing, not to mention exhausted from lying under the car in the wonderful north Texas sun last Thursday. While I'm plenty pissed at Autozone....... I'm equally upset with myself.

Btw the stupid pulley is officially a German only part, not carried by dealers. I'm realizing the only way to find one is the junkyard route.......
