Had an email from NPN saying they now have parts diagrams.

Great resource ... b*ggers have put their name boldy though every single page though, which is a bit of a shame. Thanks for posting..... a lot of those parts books I have put in our Dropbox links already and they are the original, multi-region versions, not the specific America Honda versions, so worth checking on here first.
