Personal Intro 90Q20V

[Robert Mundo <74237.1355@compuserve.com>]

Hello to all you Quattro enthusists!
 
While I don't actually own an Audi a close buddy of mine does.  He has asked
that I exchange and research all of his Quattro question on the Internet for
him.
 
His Quattro is a 1990 20valve, 30k miles, red, leather, 5-speed.
 
Currently he has a delima with a compressor bearing that is shot on his A/C
unit.  Here in town we have only one authorized Audi distributor/dealer.
Does anyone have addresses or phone numbers on a 3rd party of where he can
find OEM replacement parts without being "price gouched"?
 
Any info on high performance parts is also appreciated (engine, wheels,
exterior, etc..)
 
thanks
Rob
