Fill the tubes with Oxalic Acid (need to plugs holes to make it stay in). It will eat all the interior rust. It may take a couple days if rust is thick or deep. Then give it an interior bath in baking soda to clean out the acid, then you should be good to go on Frame Saver. Oh, the Oxalic Acid should not harm chrome, it is chrome's friend!
