65 4x4 Steering Drag Link?
 

Not sure this is the right part name, but I have a solid arm with each end looking almost like a tie rod end (90 degree offset) that connects the steering box arm to the control arm (all my part names may be wrong, I'm begging for mercy on my ignorance).

Looking for replacement part info or recommendations on rebuilding since the boots no longer hold grease. Not sure how to test if this part is worn out so that info would help, too.

Don't worry about all of the shiny oily gloss in the photo, I need to rebuild/replace my steering box to eliminate the current set of leaks.
