Thanks for the replies guys. Looks like powerflex it is then. Dojj - are the different colours a different composition for track / road etc and do I take it they come with new dished washers as well. Also still be curious if anyone has an answer as to why the rubber bushes are causing the problem - i.e. are they supposed to have different washers or another spacer etc. Boostn Capri - I am in Titirangi Auckland. Thanks again David
