When I went to change my ball joint the bolt front bushing sleeve was rusted to the bolt. I ended up having to cut the bolt and now I need to buy a new bushing but am having trouble finding one. All the ones I have seen have a flat bottom like this one http://m.oreillyauto.com/mt/www.orei...2936&ppt=C0106
The old one I have is tapered on both ends. Are they interchangeable or does my car have an odd ball style control arm?
