Not far enough. Looks like the tapered part is too large for the tapered hole.
Are these '76/'77 Bronco knuckles by any chance? They don't look like it, but the hole is small enough to be.
Is the stud for a full-size knuckle, or EB sized?
That a BC stud? I don't remember seeing anyone else making them, but haven't been keeping track either.
In a pinch you can just ream out the hole larger, so that the taper fully seats, and/or the stud sticks out the top far enough.
But I think you need to fully seat it for the rod end to fit properly, don't you? Since you don't need misalignment/offset spacers on the tie-rod side and you want the rod end to sit up almost flush with the casting, I would think you'd need the taper mostly inside the steering arm.
