The new ball style ends are a drop in replacement once the original ball studs are removed. The arms have an hour glass shaped hole so when they peen over the end it can't pull through. To remove them, drill a small hole to start and move up the set, I believe the maximin is 1/2". Have the new ones on hand so you measure them, also, be sure start out in the center. Once the peened material is drilled through, you will need to drive out the remaining stud, it's best to have them on the bench and not try it on the truck. The replacements will seem loose in the hole till you tighten down the nuts. For my '37, I had a short threaded bar made by my uncle out some pretty good material, he put left and right threads on it so the tie-rod ends would thread on. I use it for my draglink, for one it really tightened up my steering, and two, it let me adjust the length so the steering box is dead ahead straight going down the road. If you go with the new draglink, don't adjust the steering wheel on the shaft if it's not center anymore. The gear box has a tight spot dead center to help keep the truck from wandering around, once you come off that, you be making corrections all the time to keep it straight. The draglink must be the correct length, either from design or from adjustability.
