I have an Alpine 9885 and will probably need a new faceplate case soon since my hinge is split half way across. Anyway, are all these cases the same over the past few years for that similar design? Thanks.

No, not all the same. Many are similar, some are completely different.

Its covered under warranty, go to the store you bought it at, they'll give you the case for the demo thats in the board. Problem solved before dinner.
