If you know a good machinist, have them cut you left and right hand threads in some strong bar stock then use two more of the modern tie-rod ends for an easy to adjust draglink. You end up with four sealed ends that match. An alternative to machining a new bar is to find a second long tie-rod end bar, cut it down to draglink size saving the left hand threaded end. Buy a die for right hand thread cutting and thread the other end.
