Regarding the poster's question: "This might be a dumb question, are the bars tapped for a Zerk under the plug?" I recently removed(and saved) the original orange plug from my Z bar to install a grease fitting. The hole was not tapped and I had to tap the hole to install the grease fitting. Mixed emotions at altering the originality, but my car never is going to be judged at a show. That tipped the scales toward the service side of the equation and the zerk fitting went in.
