You can find the fiche of the piston assemblies there too. They should sell the piston rings? I didn't check.
Anyway, hopefully that will help.
And if you're going to pull the bearings, I have the "special" honda tool for getting those nasty trany shaft pilot bearings out that I can send your way. I bought 3 previous bearing pullers and none of them would fit around that protruding shaft seat thing (I don't know what it's called, I'm still a n00b). You saw the thread.
Anyway, give me a shout if you want to barrow it! Hopefully I'll only need to use it ONCE!
