I am celebrating the successful installation of power steering in my 73 Duster with a Borgeson box. I have a 5.7 truck engine sitting on a biscuit mount 72 k frame with TTI headers. The box is very similar in size to the Flaming River manual box I replaced.
I had to remove the torsion bar and header to get the boxes in and out. The input splines on the box are different so I had to buy the Borgeson U-joint. The lower shaft on my manual steering column had to be swapped out for a shorter power shaft and then cut following the instructions with the U-joint. I connected the box to the truck pump. I bought an Edelman line #71436 with 16 mm inverted flare for the box end and 16 mm O-ring for the pump end fitting and made it fit with minimal rebending of the line. I had to cut off part of the pressure fitting on the truck pump so the threads would engage properly. For the return line I used an Edelman #71858 with 16mm inverted flare on both ends and cut off one end and resent the other a little then used brass couplers to go from the 3/8 hose to 5/8 power steering return hose to connect to the return nipple on the pump.
I think the truck pump pressure is higher than the GM pump they recommend using as the steering now feels a little too easy, but I am very happy so far, especially since my main reason for the swap is so my wife feels comfortable driving it. If I decide later to reduce the pressure I will switch to AN lines and use the Heidts pressure reducer.
