I'm using it in my 04 Z; just to let you know, this adapter is marketed by several different companies under different names at various prices
I don't have any part number(s) for you but I bought my setup through these guys:
mp3yourcar.com
Shoot them an email, they are very quick to reply and I'm sure they will provide you with whatever part number(s) you need
I paid $189.00 for the adapter box, iPod cable, and AB-GM10 cable harness; and then forked out an additional $40.00 for the COR-HAR CD-changer harness...
