I'm confused. Why the need for a different bracket? I wanted the BR pipes on my rocker before I left the deaership with it and they put them on without a problem. Took em less then an hour.
The link you are looking for is https://www.hdforums.com/m_3037006/tm.htm The reason for Gibs bracket is to move the pipes closer to the frame. Additionally, it releaves the additional presure where the pipes connect to the engine as a result of the exagerated stock bracket.
