Looking for a power steering to manual steering Adapter

No, I believe it really is a joke... The shaft is held in the assembly by plastic shear pins, its made that way so that if you are in an accident and hit the steering wheel the assembly will collapse, that's why in the casing for the assembly there is a section that looks like a mesh (it will give and collapse also). Doing what is suggested compromises an important, if little known safety feature of your A body.
