Does anyone know where I can get a threaded brake cable adjuster that will fit into this barrel under the Bonanza swing arm? (I.D. is 1/4") I've noticed that a lot of Bonanzas have a piece of flat stock with a hole in it welded there instead of the barrel. I'd rather NOT have to weld something different because the swing arm has been powder coated. Anybody got pictures of a similar brake cable set-up?
