Hang in there. You might be able to check on this board and with the recyclers for a used one that still works. Seriously - changing the alternator was harder/longer then the AC compressor. Jack the car up, single wire yellow wire from the top, 8 bolts (I think), and you are pretty much there. Someone from your neck of the woods should be able to pitch in and help you at least see if this is it.
At worst - I believe they are about $800 new in the box. At a minimum check with one of the heavy discounters in the FAQ section.
