It was bound to happen,after my last doughnut session I noticed a bit of a rattle,so I jacked her up,low and behold the diff bush has failed.its over 15 years old so I can't complain.So I thought I might replace all the bushes while I was there.what is the best on an M standard or poly?no track days involved .while I was under there I noticed the tank straps are minging .how much of a job is that while I'm there?it might end up being a job for @Lee.i don't know if I've got the knees for it .lol
