Thanks for all the advice people, very helpful, especially roackauto. I'm not too concerned with using original parts, what ever it takes to get it legal at this stage.
Found these replacement ball joints on ebay http://www.ebay.com/itm/291421763209?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
Anyone found them to be a good replacement?
Unfortunately, car is 400 kms away at my mothers, so no pics until I make a trip down there in a months time
Cheers
Andrew
