went down to my local ford parts dealer told him my problem and showed him the bolt that is on my car and he brought out a wheel bolt reccomended by ford and it was exactly the same size as the bolts on the car!!!!!!! so i decided to go to elites and see what they had and they came up trumps with a longer wheel bolts all 16 bolts for 10 quid brand new cant go wrong! the only thing is, is that people doing this rear disc conversion is only useing the standard wheel bolt when putting the wheels back on!!!! now i know that the bolts do fit and feel solid but when you think about it you are limiting the bolt being screwed into the hub to the required length by ford because of the now so bulky rear disc. sounds abit dangerous to me i dont think fords done this for nothing. think some people may wanna consider buying new bolts only a tenner for safety and piece of mind.
