Apologies my original post wasn't very clear- I am being told that I must buy the whole of the upright for £1650+VAT per side because the ball joints are not available. But it is clear that I can buy the ball joints - but so far can not find a Morgan dealer that will replace the worn ball joints with new ones.

I am still waiting for a reply back from 2 dealers regarding their willingness to just replace the ball joints.
