Yeah I know they're easy to get since there are a few European wreckers here in Sydney so there will be some C900's around waiting to be stripped. Getting new bushes is trivial. I'm surprised that the thread for the shock mount has appeared to have stripped so easily - I set my torque wrench to the right setting (around 60 ft/lb if I remember what I read in the Bentley book two days ago), and it would have got to about 40. The nut can't be removed with finger pressure and a spanner will turn it but it needs a fair degree of force. It's just not moving anywhere, though I guess there is some bush lube, etc. gunked into the thread otherwise I should have been able to see little bits of metal around the outer side of the nut where the thread of the 'bolt' on the a-arm comes out. hmmm I'm hoping that the a-arm doesn't have to be replaced and just for a dudded thread it's a bit radical but since the lower shock mount is fairly important (!), that pushes it up the priority scale.
