Will the traction bar be a one-off deal since it looks pretty permanent with the welding or is there bolt on thick bracket that cups around the control arm and using the existing holes to use bolts in the works for production also?
For example like that big hole closer to the frame mount, there could be a thin solid bushing with a hole for a thick bolt like a motor mount and use the other remaining holes for more bolts and you could have the extended tab like you have here for the heim joint
Just speculating I don't know a whole lot about the geometry needs for this to work. Great stuff though you've been busy!
