I kinda did the opposite: I installed a TBI 350 with its power steering pump. I used the TBI's pressure hose to my original power steering box. I cut the O-ring style fitting off the TBI hose and flared it an hooked it up to my gear box. Of the return line, I just loosened the hose clamps and swapped out the gear box portion of the hard line.

If you were switch just the gear box on with the original style PS pump and you remembered to grab the hoses (or got new hoses for that new box) you might be able to do the same sort of thing by flaring the PS pump side of the hose (might be tight do to the bend, but worth a shot)
