I just purchased an autozone alternator and it went in without a hitch.
And if I can give you some unsolicited advice for swapping it out (This is for V6 car):
I read some of the how-to's on this site and found that neither those nor the Haynes manual recommendation was very good. Some of the things that others suggested caused me to waste a significant amount of time. Here's how I did it:
1: Jack up car, remove positive cable from battery. 10mm nut here.
2: Remove right wheel and splash guards. 19mm wheel nuts, 10mm splash guards
3: Remove serpentine belt
4: Disconnect right tie-rod. 13mm or 15mm, can't remember
5: Drop Y-Pipe. 15mm bolts here
6: Remove the two alternator bracket bolts. This is accomplished by guiding a 12" extension and 13mm deep socket onto the top bolt. The extension and socket should rest immediately on top of the rear exhaust manifold and should thread behind the EGR tube.
7: Use the same socket/extension combo to get the lower bracket bolt. It should also thread in behind the exhaust manifold (very tight fit.)
8: Remove the two 10mm bracket bolts. One can be removed with a deep socket, the other will need a 3-6" extension plus the deep socket.
9: Using a pry bar, pry out the alternator. It should come right out. Wiggle the alternator until you can lay the face of the alternator down so you can access the rear of the alternator. Remove the 10mm main bolt and main power cable (did you disconnect the battery??), bosch wire connector, and B+ wire. The B+ wire can be removed with a small flathead screwdriver.
10. Installation is the reverse of the removal. Expect to spend an afternoon on this project.
