[Mart]

Without a scale to judge dimensions from, I think the smaller ones are the normal ford type drag link / track rod ball studs. The necking is typical. The bigger ones do not have the necking and (in my opinion) would cause binding if used as a drag link / track rod link. They may be some sort of truck application, or not Ford parts.

I think tie rod may be the US expression for track rod.
