If I had a bent axle I'd be getting a consistent shake, not just at 100

Agreed, anyone who's had a wheel out of balance can attest to reaching a given speed at which the shaking starts and may even have experienced a higher speed at which the shaking seems to subside.

Yeah fair point. In my mind wheel balance / driveshaft balance is more of a harmonic resonance type thing that would manifest at X speed... whereas if something isn't spinning in a perfect circle (ie bent axle / tyres out of round) you'd experience that vibration at all speeds.
At this point I'm probably just going to take it to somewhere reputable and ask them to run a fine tooth comb over the car until they find the problem.
Thanks for your input folks

It seems that you have already changed all the usual suspects but sometimes it's very difficult to find gremlins like you described. Although a clutch balance issue would show when you are in neutral at 100k as the engine is running down in revs. Gearbox may have a shaft bent but that's not likely. Tailshaft is next on the list... Bent or universal gone. My old 80series landcruiser had universal gone in the front driveshaft and shook like hell... New shaft fixed it. Give the shaft a twist and check for movement, it will show up a dud universal.
Good luck finding it, you seem determined to get to the bottom of it but sometimes it just is!
