First welcome aboard!
We'll do our best to make NiCo and the 320 Forum your one stop shop for everything Datsun PL-320. I have a fleet of 320 in various states of repair, restoration, and running conditions. So if you have a question, need answers, parts or technical advise, NiCo is the place to start.
Okay, here we go.....
-Before getting into the parts piece have you cleaned up all of the steering components? I think you will find that after a thorough scrubbing your parts list might decrease a little or simply realize a less expensive pieces/part will work.
- Here's the steering schematic- not much to go wrong here.
I'd start by cleaning up the steering linkage-
And the front axle/hub assembly
-For the parts you are looking for a Datsun 520 should work, but do not quote me on that, I am not that far along on my one steering system. Let me do some research and see if I can find anything for you.
- Tie Rods - a 520 should work; however, I think you will find you only need boot covers - available through Whiteline. Just follow their instructions for how to measure the dimension. Again, should be the same as a 520 and maybe even later model 521 and 620s. Here's a listing from eBay, price seems reasonable

- King Pins - several available on eBay right know. Again a thorough cleaning of backside of the front axle/drum assembly might reveal you only to change out the grease nipple and apply new grease.

This listing is from Thailand, but I have had ZERO issue with purchases from Thailand and I have made more than several from a couple of vendors.
- I would definitely change out the upper bushings. Just a note there are not lower rubber bushing on a 320. Here's a link to an eBay listing. You'll need to order 2 sets

Give me a few to find the link to the service and parts manual.
