It looks like the part # is SBA334800231 But you'd better check that number to be sure.
New Holland says it is still available but at $128 I would be tempted to look for another source.
Take your old one down to your local Napa or favorite parts store and ask them to try to match it up.
They can measure it and compare it to others in the book.
You would be surprised at how often you can find a generic tie rod end that will work.
Otherwise you could find one that matches the taper and weld it onto your tie rod.
I have done that several times with good results. A little grinding, a little bondo and some blue paint and you are good to go.
