I have been wanting to convert from manual steering to power steering for a long time now. I did a lot of research regarding a steering box and everything I read pointed me to the Delphi quick ratio power steering box. It was pretty pricey, but well worth it. With all the parts in hand I installed the box and rag joint in about two hours. Because of the different ratio I had to rotate the steering wheel a 1/4 turn. I'm still a bit of an amateur, so all said and done, Steering Box, Pump with brackets and moving the wheel took me 5 hours to complete.
