Request For Audi 2.8 l V6 Crankshaft Bearings Source

[Pbadore at aol.com]

Has anyone sucessfully rebuilt an Audi 2.8l V6 crankshaft?
I am unable to find a source for rod and main bearings to
permit grinding an Audi A4 V6 crankshaft undersize.  The
Audi A4 shop manual lists dimensions for undersize 
crankshafts for both the AFC and AHA code V6 engines but
Audi's USA  factory parts division only provides standard size
rod and main bearings. Any help would be appreciated.
