06 LBZ PCM Part Number

Does anyone have the part number for an 06/LBZ PCM?

Where can I purchase one?

Thanks in advance.

Not sure about the P/N, but I saw a post on this site which may help: http://forum.efilive.com/showthread.php?t=5999

Service # 12606126, the price in that other thread is a good one. They used to be over $400 a year or so back.

Cheers,
Ross
