Please just use Sprinter or Corolla parts. So much easier, there is no need for modifiacions. The S13 rack is for powersteering anyhow.
Get any steering rack from a KE70 van, KE70 or AE71 sedan, or AE86. S13 is the wrong part!
The lower control arms should be from a Toyota also, unless you are trying a funny hybred Nissan coilover setup.
