When I first read the title I thought you meant upgrading to "non power steering."
Yes, there's several people that have done the "notch." A good mallet and oxy/acetylene torch is something people have used. Others have simply cut and rewelded.
I'm not exactly sure of the procedures they used but I think before you go through all of that, you need to make absolutely sure all of your front end is checked and/or redone. If you have any worn parts power steering is going to accentuate that sloppy feel.
