Do I have the new or old style antiroll bar?

Hi guys  

My front anti roll bar has started knocking so want to change the bushes and read about some of the fabias being fitted with bars which had plastic retainers around the bushes which would perish and snap off in time. I just got a photo of mine and was wondering if someone could tell me whether I have the old plastic type or the revised type with metal retainers?

Thanks
