Nissan Repair: AC Compressor Clutch Bearing, clutch repair, nissan maxima

Question
I have a 2000 Nissan Maxima, 3.0 V6. It has a Calsonic AC Compressor and the clutch bearing is going bad. I found a place which ordered the bearing for me. Although the outside diameter was the same the inside diameter was smaller then the orginal bearing, not to mention the "height". I've been searching the net for a clutch repair kit but can not anyone who has what I need.
Q: Do you have any references that I can contact to purchase a ac copressor kit. Any help would be grateful.

Answer
Mike,

For factory parts try courtesyparts.com

It might cost a little more than the discount places, but they are a real dealership that sells for the jobber rate, on-line.  

Discount placed are as follows:

The aforementioned are a few I use.  Use a search engine like google and find more...
