Thanks Col, I came to the same conclusion and have booked it in at a place I trust for Monday morning! I suspect castor is wrong. I can get the toe-in close in the garage but even when I have that adjustent close and adjust it off a bit to the right it still drifts left! I marked the castor eccentrics but now of course am not 100% certain that I didn't swap the eccentrics side to side by accident.... We'll see.I would get a wheel alignment done John to make sure that the front wheels are pointing in the right direction. Doesn't have to be out far to make a big difference.
The steering is noticeably lighter - rather more positive camber with the new lower bushes I reckon.
