When I made my adj drag link I went to my machinist with the (usual chev truck suppliers) pinch bolt offshore made the rod ends, he asked me to throw them away as he saw some failures with those.
Ended up with rod ends from Speedway, bought their internal threaded tie rod and a right hand tap…
Only down side is the tie rod has no hex on it, takes a bit to get both ends aligned and tight in the right position.
As I have mentioned before, if you tap a hollow tie rod start with the rod 1/2” longer than needed so you can get the tap aligned and cutting straight with material to spare…..then cut to length and finish tapping, use tapping fluid, don’t go way deep with the tap right off, check your threads with the rod end as you go just deep enough or the end may feel a bit loose in the threads.
