Some generic centerlinks have become avail in the past few years for under $100. Got mine from Southwest Speed, a circle-track supplier.
When I was searching for tie rod ends, the tough detail to match was the location of the grease fitting. It should be on the flat opposite the stud. The ones that are avail have the fitting on the very end, which is so close to the frame, it can't be accessed.
Correct tie rod end boots are now repo'd if you want them to look correct. Inline tube is the source.
