mancini tube upper control arm failure....

Wow! I stumbled on this site while shopping for control arms for my Dart, good thing too. Judging by the picture on the CAP website, I was shocked at how sloppy the welds looked on their lowers. Giving CAP the benefit of the doubt concerning their welds (not seeing it in person), there is simply not enough material at the ball joint socket. A gusset is needed like on some of the magnum force versions for safety. Still though...did the arm cause the accident or did the accident break the poorly designed arm?
