Thanks for all the info you guys have contributed.
The main concern is with Ball Joint Application. Frank Salerno, Director of Safety Inspections (now retired) of the National Street Rod Association sent out a memo Sept. '10 to all NSRA Safety inspectors informing them of this misuse of parts. It just so happens that it involved the aftermarket Mustang II control arms.
The concern is with the Ball Joint application and not with the control arms or the Mustang II IFS. He had seen Volare UPPER Ball Joints installed in LOWER controls arms fail because LOWER ball joints are heavier and have preload built into them that the UPPERS don't have.
Any more engineers out there have ideas. Thanks
