B275 tie rod end replacement issues

Hello, this is my first time posting here, so please bear with me if I break any of the unwritten rules.

Friend of mine has a B275, serial around 19k. 1955 or 56, something like that.

Anyways, he was driving it one day and it all of a sudden got to where it would not turn any further right than center.

So we took the side cover off the steering box and for whatever reason, it seems like the worm or pawl or whatever it is on the spline-end shaft that runs inside the steering box horizontally lost the correct timing with the screw end of the steering column shaft.

So as a cheap, temporary fix, we decided to just rotate the drop arm on the spline and fab up a new, shorter drag link. His range of motion will be reduced, but he'll at least be able to turn some in either direction.

The problem is that the original tie rod ends that the drag link threads onto are .625-19 threads per inch. Left hand thread for the rear (drop arm) and right hand thread for the front (steering arm).

My lathe will not turn 19 tpi and my chances of finding a .625-19 tpi LH tap are about 0.0% From what I can tell, the only thing mankind ever made with that particular thread is IH tractor steering parts!

Ok, so the seemingly simple solution would be to just replace the tie rod ends with new, non-IH parts. The joints on these are pretty worn out anyways. Something with a bit more common thread that, ideally, I could find hand taps to match.

So I've got the tie rod ends out and they are tapered fit into the steering arm and the drop arm. As close as I can measure with a set of calipers, the taper is about .125" per inch. Is that correct?

If so, what tractor or car would be a good match for replacement? From what little I've seen about it on the internet, Ford 9N steering tie rod ends are the same taper, but I'm really groping around on this. They do have a somewhat uncommon 11/16-18 thread but nowhere near as rare as the original International ones.

Any ideas?
 
I do wish you luck, but just saying here, it seems like you're going through an awful lot of work and expense when the right thing to do is figure out what's wrong with the steering box and fix it. It's not even going to work right when you do gather up all the parts anyway, and frankly, it will probably do the exact same thing all over again after you've gone through all this effort.
 
The threads believe it or not are BSP! Went through this some time ago on my 434 when trying to get a back up nut. Its BSP, but parallel thread not tapered.
But fix the steering box! They are a very simple set up.

Probably, but I still need to replace these tie rod ends no matter what.

Right now it has no steering. The drop arm, drag link, and steering arm are off of the tractor. The tie rod ends are out of both the steering arm and the drop arm.

If I replaced the steering box right now, I'd still have to find some new tie rod ends.

I'm just not interested in going with original International tie rod ends.
 
I went ahead and ordered the Ford 9N tie rod end replacements.

I'll let ya'll know if they fit or not, just in case someone has a similar issue.

Should be relevant to other tractors, as I'm pretty sure that steering arm is used on a few other International tractors like the 354
 
The after market supplies both tie rod ends and drag link ends. They cost more than twice of Ford parts so you may be on to something.
