alternator replacement

wondering how hard it is to replace an alternator in a 1996 cavalier z24. and if possible, i was hoping to get some instruction on how to do it, so i don't mess anything up. pictures are welcome, and also if anyone has a used alternator they want to or are willing to sell, let me know, and yes it would help if it worked.

If it is anything like most cars, you will:

1) Take off the serpentine belt
2) Unbolt the alternator
3) Unplug the alternator
4) Bolt in new alternator
5) Plug in new alternator
6) Put serpentine belt back on

alright thanks.
