2379-DJU wireless and bluetooth upgrade questions

[FritoBandito]

Hey folks,

I'm hoping I'm not being a complete boat anchor asking these questions. I've been lurking/searching here trying to figure out which part numbers I need to upgrade my 2379-dju to the 2200bg and bluetooth and getting confused about which parts I need.

First off, what's the correct part number to order the 2200bg?

Then for the bluetooth do I need 91P7315 or 91P7319? I found 13N5666 for the clear plate but it doesn't come up on IBM's site. Is there a new part number?

Lastly, is it best to order direct from IBM or is there a preferred thinkpads.com vendor?

Thanks for the info guys.
