I believe I have just what you are looking for. My only question is if your steering box is the same diameter output shaft as mine. I know there were at least two different sizes (i have two) let me know and i'll go measure mine.

edit: I have been thinking and I remember the steering gearbox i switched out was a different size but i don't think the output shaft was different. In any event if you are interested in my old pitman measure your output shaft and let me know
