The Heritage Handlebar part# is indeed 56902-08, and is a direct replacement for the 2009 FLHRC stock bar. You do not need any additional parts or wire harness extensions. Be carefull with the brake and clutch lever switches that operate the break light and input to ECM for cruise control operation, they are easy to break. I would also advise you to remove main fuse before you plug and unplug the twist grip sensor and other plugs in the headlight nacelle.
