I think all size 23 steppers are the same. http://www.usdigital.com/products/ms23/
The only thing I can't tell you is the length.

I don't know for certain, but the torque rating and the 23 in the part number indicate it is most likely a nema 23 motor. It would be about 2.3 inches in diameter, and have 4 mounting holes spaced about 1.8 inches apart.
