outer tie rod stud too short.

[HO455]

After searching for at least an hour to no avail I now throw my dilemma out in hopes some one can confirm what is going on with my Burban. It is a 67 with disks and I believe 71 - 72 spindles. My question has to do with the outer tie rod ends. They don't have castellated nuts on them. Nylocks have been installed as it looks like the stud on the rod end is too short for the castellated nuts with a cotter key. Is this possible? It seems like the spindle and the rod end have the same taper. (I pulled them apart and all looked correct)
