Full workshop manual is available for free here:

62 x 60 bore/stroke. Not sure if you can buy rings separately but a set of new pistons/rings/pins is only $85.

Not sure what happened with that link, it should have gone to the F5A pistons. Their website must be a bit broken. If you search you'll find them.
They also sell genuine rings, but the price is more than the piston set! (Hope this link works!)
