I must say I was unaware of any differences in the rear display housing of 15" aluminium PowerBooks. I know they have slight differences regarding antenna cables but as far as I know they all fit each other. If Mord is correct, the only high res units are the last-of-line 1.67GHz Dual layer superdrive models. I was under the impression these were still physically the same size as earlier models.

MacBook Pro housings are different and will not work on PowerBooks.
