Interesting. I hadn't herd of that before. So basically they were
defeating the simplicity of Rack & Pinion Steering by adding idler arms
on some new mounting location. I wonder if they were just Alpine idler
arms moved forward for use with the rack. Does ANYONE have a picture or
drawing of this? Or is there anyone currently using this system? If
there are any pictures of this, could someone either send me these in
mail (one at a time please) or have them posted up on the web. That
would be great !!
