Trackpad ribbon cable replacement?

I have been given a iBook G4 by a friend that had a harddrive failure and was too expensive to repair so she decided to get a new MacBook instead and gave me this old one in a bid to "convert me" to the Mac way of thinking :) Well in my effort to install a spare HD i had ,and following a guide that was not the correct one apparently ( not from this site) it looks like i have torn the ribbon cable for the trackpad accidently ( the guides here mention it,the other one didnt) so I am looking for a fix or replacement , the Apple store couldnt help with either , of course the trackpad can be abondoned is my guess and just use an USB mouse but i'd like to fix it if it is worth it $$wise.

thanks in advance for any ideas .....
