EDIT: Ah crap, sorry, I'm stupid. I gave you instructions for retaining the A/C. You want to know about the power steering...
Anyway, the power steering is pretty simple as well. Use the H22's power steering bracket. The Prelude's power-steering pressure line is slightly different than the Accord's, so you'll need to cut the end off of the Accord's line and then replace it with an H22/H23 piece in order to get it to attach. You could try using hose clamps, but I sure as hell wouldn't recommend it. I'd have the new end TIG-welded in place for good measure.
Do some searching on the net. Somebody out there probably makes a kit for this.
