The conversion from power steering to manual is simple - remove everything except the center link. That means removing the pump, belts, hoses, ram and the ram bracket. Your steering will be now be called "armstrong power steering" because the ratio, although usable, will be a little tighter at 16:1. (A manual steering box has a ratio of 19:1.) There will be no adverse affect on any component. If this is to be a permanent conversion, you may want to install a manual steering center link, steering arm and box, otherwide - drive it.
