If there is at least half an inch of good-quality thread inside each tie rod end, you can probably re-use them, provided all of that thread is engaged when the steering linkage is correctly adjusted. The ball joint must be tight, not worn, however. In any case, I'd be surprised if Greenfield did not have tie rod ends as spare parts. However we can talk about that when you post pictures of your machine and its individual components.
I don't think wrecks of 12-32 Greenfields are all that rare, but their condition might easily be worse than the one you have.
Once we understand which parts need to be replaced, that information can be summarised and you can discuss it with Greenfield's service department by telephone. Provided you have done your homework and know what you are talking about, most reports I have seen say they are quite helpful.
