Anyone know where I can buy a bush for the gearbox extension. Cheers Ian.

You must be able to buy aftermarket ones for TH350 at least if the listing above is correct. Here is a Trimatic one:

Speculate Trimatic, Aussie M15, M20, M21 are identical? Just because the yokes are…

By the manual yoke and bush are a matched set as I recall. Not that I stuck to that. But then I’m still chasing a minor vibration. I’ve got pinion angle sorted and tailshaft appears to be fine.
