Thanks for the pics NR. That is what I'm thinking on doing as well before mine breaks, but was hoping that the end just unscrewed so I could just thread on a Hyme joint. I would hate to break off a perfectly good end to upgrade it, but that is what I might have to do.
An other alternative that I did see on YouTube showed that you can back up the molded end with a small hose clamp to keep it from splitting where it is molded to the rod. Not sure if this is a permanent answer, but couldn't hurt reliability wise.
