Uhh, you don't actually drive that on the road, do you?
I'm all for some home brew stuff but, i'm not sure i'd feel real good about cruisin down the highway with that.
But i've always had a bad vibe about welding those arms. I have been known to heat and bend the arms, to make them high steer. But a fair amount of research went into finding out how to do it the right way. (heat, bend, pack in sand and let cool very slowly. to put it briefly)
You already have the steering boxs. All you need is arms and tie rod and drag link.
Anyways....we still don't know what kind of wheelin, if any, this guys going to do. Alex....where did ya go?
