383 power steering in '72 A Body?

I have a '72 Valiant and am wondering if the power steering box I have (a Firm Feel unit) would still fit if I swapped a 383 wedge from a 1968 B-body in to replace this 360 small block I am using.

I know the oil pump is somewhat in that area, and just wondered if non-power steering was all that would fit a 383/A-Body setup.

Any information will be appreciated. Thanks in advance...
