power steering

i tried the search for hemi swap steering on here and google and just leads me to hemi swap or old threads that don't mention steering , other than rack and pinion is there any power steering box /header combo that will work for a 72 duster? borgeson shows a box that looks close to the size of a manual box but hard to tell without seeing dimensions . my wife would be driving it to work probably once a week so I wont to avoid manual steering , thanks
