My roomate has a Powerbook G4, and as apparently happens, the casing around the left hinge has cracked so opening it allowed the hinge to exert force against the display back and force it to split. In looking for replacement parts I came to the conclusion that it is rather expensive to fix, and came up with my own solution (albeit an unaesthetic one). I took 2 alligator paper clips (Staples brand binder clips) which I measured as having a 5/16ths inch base. I cut the round parts (where the lever is inserted into the clip) off on one side, and clipped it to the offending part of the display case with the recently flattened edge on the inside of the display. See the pictures below, and feel free to
email me any questions.
Please note that this is a first run. I intend to get my dremel and cut the clip closer to the base so the pressure is applied about halfway between the outer edge and the display itself, right now it is almost right at the display. My bottom clip also has a bit of metal I used to wedge it open. I did that clip first, and found that while it was more work, it looked better with that snapped off. Cutting the rounded parts off of the outside is prbly also advisable, though I was very careful to make sure there was no sharp edge making contact with the case. Any improvements I leave to you, though if you find something that works particularly well please let me know.
