• Anybody know what the AAZ overbore numbers are? Also, what version of the Bentley manual covers the AAZ?

• Do you need the part numbers, or the actual sizes that are available?  If it's the sizes, the standard piston size is 79.48mm, the 1st piston oversize is 79.73mm, and the 2nd piston oversize is 79.98mm.  I asked the same question about the AAZ manual.  Here's the thread:

  I just bought one from Amazon.  It covers the AAZ just fine.
