88-98 all power to man. doors?

Hey guys how hard would it be to convert my all power doors to manual locks and crank windows? I am tryen to convert my truck down to as few wires as possible and im doen a sheet metal interior and i would prefer crank windows. Just to clean up the look a little bit. So how hard is it? Im sure i gotta pretty much gut the door and start over? Or do i? Let me know fellas thanks!
