You can make the draglink adjustable if you can thread a rod. Find a second steering rod, the long one from tie-rod to tie-rod, cut off the end with right hand threads, and rethread it at right length. This way you only need a standard right hand die. Left handed dies are harder to come by.
You gain two advantages with this, one is modern sealed ends, the other is the ability to center the steering gear box. Both make the truck better to drive.
