Boy, it's been 5 years or more since I rebuilt thosevfront ends. I only had one bad tie rod end and just happened upon a good used one. The problem with my front nds was that all the spindles, center shaft & housings were sloppy/worn out of round. I had everything built up & machined down and put bushings in all the housings. The thing I still need to do is get the play out of the gear boxes.
Sorry I can't be of help with a new tie rod source. We have pretty good machine suppliers around here, but I don't expect I hag access to anything different than you.
