I am using a front frame clip from an '86 Toyota under my autoX project. I have converted to rack and pinion using a shortened Miata rack. All is good and everything feels great except the long Toyota steering arms are a touch slow. It is quite convenient that these spindles use a bolt-on steering arm. Before I set about building my own, I am curious if any other lengths are available. Power steering arms vs. manual? Newer or older generation vs. my 86?
