I've done a nut-and-bolt rebuild on my 88in Series III, including a new chassis. Now it's finished I am still always fighting to keep the vehicle in a straight line when driving.
All the steering ball joints rods and relays are new. Both sides of the axle have been rebuilt using all-new parts, including swivels. It's riding on parabolic springs and ESP 3000 dampers.
I am not a mechanic but did do everything by the book. Is there some geometry checking that I should be doing?

I don't think this is a steering geometry problem. To get the effect you describe the geometry would have to be a long way out and you would have worn out a set of front tyres in a few hundred miles.
I suspect that the steering box needs adjustment. The adjuster is on the side of the steering box facing the wing. You just need to slacken off the locknut and turn the adjuster screw inwards until there is no play when rocking the steering from side to side. Always make sure you do this with the front wheels lifted off the ground (don't forget to use axle stands). After the final adjustment, make sure there is plenty of oil (EP90) in the steering box before you adjust it and don't forget to re-tighten the locknut when you've finished.
