Those are my pics. I am glad someone can get some use from them.
My personal experience: big sway bar lead to deformation of the subframe around the brackets. So I had some backing plates welded it (as Stazi just described), but the welds cracked before long. In the end, I had the subframe dropped out of the car and the mounting area was re-fabricated as described in the photos. No problems since, and I can't really see how problems would arise in the future, since the fabbed C-channel mounting structure looks very strong to my engineering intuition.
