Oh, you mean the bottom screws you would use to mount in the enclosure?
 They are exactly the same distance apart (about 1.5") as the front two
side screws, but offset about .5" back from the front side screws.

There are two screws (of the 4) that mount the circuit board to the hard
drive casing that are roughly 3.5" apart.
