I had my car MOT'd on Saturday by a Morgan dealer, he advised that there was some play in my front suspension but nothing much to worry about yet. It would probably be ok for another year or two yet!
So now I'm thinking of just changing to the basic SSL front kit of springs and shocks and leaving the king pins etc alone for a while longer.
It sounds as though The Rutherford set up would require new king pins and bushes at the same time which I think would be unecessary for now.
I don't push the car hard and the handling for my driving style is pretty good, I just need something that will handle todays poor roads better.
I think, listening to you guys, I'll go with a DIY fit of SSL fronts and maybe some new shocks for the rear while I'm at it :-)
