I'm just about to take my first ever plunge into eBay, as the wiring on our power supply has cracked just before the connector that plugs in to the iBook itself. But if any member has one gathering dust somewhere, I'd much rather give the money to you!
Can't help personally but before entering the uncharted depths of eBay you may like to look up bookyard.com who specialise in parts and other bits for current and older macs.
