iBook clamshell hard drive upgrade

Hello, I have an iBook G3 clamshell 366MHz with 576MB of RAM and I would like to install a larger hard drive than the stock 10GB. I understand that this is an invasive repair on this computer, but I have been working on these G3 age computers for quite some time now. I want the drive to be 80GB or more. Does anyone know what kind of hard drives are compatible with this computer?
