If your 1.33 iBook is also 14", then yes the LCD panel will fit. I believe that you will have to use your old cables tho. Its been awhile since I worked on an iBook. The 12" LCD iBook G3-G4s were all interchangeable.
i'd say 50/50. there were 2 different cables that i'm aware of. the logic board ends were the same, the panel connectors were different (one slim, one wide).
better odds than lotto, hope it works, best of luck.
