Ball joint, positive camber on drivers wheel now sorted

[titch]

Was looking at the car the other day and noticed that the drivers front wheel looks like it is leaning in at the bottom slightly. I have never noticed this before and recently i have just changed the ball joint, i know the ball joint diameter differs 16mm and 18mm mine are 18mm. But i didn't realise that they differed between non power steering and power steering models, and after a quick look on google the non power steering ones are shorter from ball joint to bolt holes, now if i was given the wrong one a non power steering one and fitted it to mine as it is shorter ( i don't know by how much ) could that cause this do you think ?

And does any body know the difference in length between the 2?
