someone has been nice enough to host pdf documents of just about every mazda service book he could find. been looking threw it all morning and he has part catalogs and service manuals even some hayes manuals. BUT DO NOT DOWNLOAD THIS STUFF
use it as a reference if too many people download and print off everything they see he will bring it offline which no one in need of this info wants so donate if you can and take a look you might learn something
