Did you happen to read the description of this item on that auction? The first clue is the word 'big' in the auction title.
"The "Big GM" Power Steering Box is commonly referred to as a 700 series Saginaw box. It was the dominant power steering box on almost all GM cars through 1977 & about 1/2 of all GM cars from 1978 to the early 90's. This box is distinct for its square, 4-bolt housing cover, as opposed to the round, ring-retained housing cover that the smaller GM power box has. This box features a 1 1/8"-32 spline pitman arm shaft."
The S10 box is not a 'big' steering box...
