1963 - 1966 Chevy II Nova Power Steering and Manual Steering Differences

While converting from power to manual steering and swapping out my steering box, I documented the differences in the components used. Here are some key points I took away from the conversion:

• The pitman arms are different. The manual arm has an integrated ball stud to connect to the center link, while the the ball stud for power steering unit is part of the power steering control valve (PSCV). There are also some differences amongst manual pitman arms - some of them have a zirc fiting, while others are sealed unts.
• The idler arms, as well as how they mount to the frame, are different. The power steering idler arm mounts to the front clip with three bolts, while the manual arm mounts with four. The different units share three holes of the holes. The front clip on my car had the forth hole already drilled in it.
• The centerlinks are different. The driver's side end of the power steering center link is thread for the PSCV. The driver's side end of the manual steering centerlink has a hole for the ball stud on the pitman arm.
• Power steering and manual steering use the same steering box.
• To remove the steering box (the original had huge deadspot), lots of under car clearance was needed. My rocker panels were approximately 23" off of the ground.
