650 clutch baskets?

[imago]

The 650 developed a clunk/knock/rattle when hot and under load. I didn't sound deep enough to be a big end or main and didn't get any worse through the throttle positions, hotter, faster etc.

So, I stripped out the clutch and the basket to gear springs are past their best to say the least. I'm pretty sure I have a new basket somewhere, but in case I haven't is their anyone who rebuilds these?

I'll get it rebuilt anyway as the basket 'fingers' don't have any steps on them and the gear itself is fine. So it'll be good to have for the engine out of the one which is getting rebuilt, or as a spare for the runner.
