Tie rod ends for models FC, FD, 61.
Studebaker part numbers, for complete tie rod end.
Right 165724
Left 165725
The number that are listed in my Toledo catalog:
ES5
Although catalog doesn't list, I would imagine would actually be ES5R and ES5L.
I think most of the aftermarket manufacturers like TRW etc., used the same numbering systems.
I do not have any, the earliest that I have are ES25, which are for 1934 up.
You'll have to call places that deal in older chassis parts to try to find them. Or Gary's solution seems workable.
Good luck
