Thanks for the note. It looks like there is lots of great information on HT.
Here is a picture of one of the socket assemblies. On the upper / long one, the tie rod end attaches to the pitman arm assembly, with the other end fastened to the wobble assembly with two bolts.

The other (lower) one has a bit shorter tie rod end and is located closer to the knife.
I have also attached a link to the parts manual:
The parts are on pg. 21 (Pitman and Wobble Arm Drive) - reference #8 and #16 on the diagram.
I'm located about 40 minutes from Port Huron, Michigan. These parts are small enough (and not too heavy) that shipping from distant areas (US or Canada) may be an option.
Thanks in advance to anyone who might be able to give me any leads on these parts.
