Steering?

Some tentative steps towards power steering for the Chief. I had gotten a 605 box from Rock Auto a few days ago. Today I started disassembling the spare column I have for the car. I removed the column tube and cut the shaft at the box connection. I made some rough calculations of the length and ordered a universal joint with vibration damper to connect the shaft to the new box. There are an awful lot of considerations involved in this. I hope by taking small steps I don't get overwhelmed.
