It is confusing and what you need may indeed depend on how they were installed the last time it was done (like MB Doc said). Best to take them off, or at least separate them and turn them a few times to verify RH or LH.
It also looks like there is a break in the application (two different outers & inners depending on chassis # ?).

When I did mine last, the whole tie rod assembly (inner & outer w/sleeve) was plenty cheap enough that it was easier just to replace the whole thing, and I didn't bother to pay attention to which way around I installed them since it didn't matter performance wise, and I knew if I had to do them again I'd just replace the whole assemblies again.
By replacing the whole thing it was very easy to match up an accurate length measurement from old to new while they were out. The car tracked perfectly when finished and in the long run (tire wear, etc) it turned out that I never needed to get it aligned.
