Manual steering box issues

[coyote72]

Has anyone ever put a two wheel drive manual box in place of a 4x4 manual box? Aside from pitman arm differences is there a ratio difference? I have not been able to find any 4x4 manual boxes (going into a '72 K5) but two wheel drive boxes are plentiful. I enjoy the manual steering, and don't want to go power. It seems my options are to use a two wheel drive box and find a pitman arm that will work with the steering drag link, or go to power steering. Any ideas? Thanks!
