Vising the 'spare' tie rod in the parts car's steering knuckle, I was able to break loose the end I'm interested in learning about. It's a 19mm LH jam nut, jamming a flatted squeeze collar (looks like a nut, but it's not) against the threaded and slotted (pinchable) body of the rod. Easy to take apart in fact, if it's not too rusted. Now I'll move on to the ones I'm interested in mix-n-matching. They've been soaked in penetrant since yesterday.
