hiya , you need to bite the bullet and just get a new roll bar from fiat . they are a 150pounds . have just done mine. the bushes are fixed to the roll bar. don't forget to buy new drop links also. you can get these for 20pounds from euro car parts. you will need to lower the front sub frame a bit also if its a diesel like mine , I don't know about petrol models. what a difference it has made ! no more banging from underneath all the best Conan
