Yup, I went that wrought and wound up getting a rebuilt box cause the used one leaked. There are two differant boxes, the size of the input shaft is how you tell them apart. I think it is 3/4" or 13/16 or something like that. Autozone #858563 1978 IH Scott II 179.99 +156.00 core. Comes without Pittman arm though.
Or try
http://www.car-parts.com There is three pages of them from $45.00 - $175.00
