Tom, it's all modified Prius parts. I figure if you can modify them for a Mustang and get it to work, you can modify it for an MB too. It was a thought/suggestion, because the electric systems do not require modifying for a PS pump, hydraulic lines, etc. Nevermind replacing the rack. You can replace the rack for fewer turns if you want, and Hoovie's issue might be that someone did replace his rack with a tighter one, making it harder to turn without assist. Or he just doesn't like the manual steering in it.
