I have yet to find that point. If toyota used cast iron for the steering parts then it would be dangerous. But seeing as they are cast steel there is not really any problem with fabbing your own. Hell I know all-poo sold fabbed arms and I *think* Marlin did for a short while as well.
im sure it does work and i have seen the all poo arms. i was referring to when i had posted on this subject sometime ago and i was told i would still be snapping that arm from overflexing. i guess the main concern are the wleds gonna hold?
