Well just skimming over the datasheet, you need a 96x32 pixel, positive, transflective, FSTN 'custom' LCD. *Custom* because of the custom characters at the top. Serial interface, requiring external caps for the Vboost.
I don't think you're going to have much luck there mate. I only have a couple of suggestions.
1) Get onto a generic LCD manufacturer (topway, or another one form china) and send them the specs to get them to start manufacturing it. Very expensive and only worth it if you need LOTS of them.
2) Use a generic 132x32 graphic LCD, with an external micro to translate the serial commands/data from the original LCD's cammand set, to the new LCD's command set. The micro could also generate the 'custom symbols', altohugh they would be in dot-matrix format and so not be as clear.
There are 96x32 LCD's, but 132x32 or 120x32 is more common. As for 'FSTN' (black pixels instead of the horrid STN blue/grey) I'm pretty sure they are available.
Manufacturers would include:
BATRON
EVERBOUQUET
TOPWAY
Getting the same dimension will also be tricky, COG design is mandatory. But an 'adapter board' with the micro could be made <2mm thick and attach to the back.
Sorry for the bad news, but that is just my opinion. There are loads of special custom LCD's about, but the fact yours is one just makes it even harder to find a suitable replacement.
