mancini tube upper control arm failure....

I have CAP ucls on my Barracuda, I'm not sure what caused the weld failure but the 3rd pic down shows the front tube of the control arm pushed back. The forces working on that ucl are more front to back..it locates the upper ball joint. All the major force is on the lower ball joints (I've never lost the upper ball joints but have lost the lowers). I would love to see the lower control arm. But I do agree the weld should have held..I'll be watching mine and maybe have a gusset plate TIG welded in.
