I don't know anything about the frame but I have a little suggestion. When you talk to the guys who sold you the car or Chrysler, use 'UNSAFE' about every fifth word. That's code for I, or my heirs, are going to sue your *** off if this defect causes an accident. Defective products placed into the stream of commerce are covered under strict liability as well as negligence. Under strict liability you don't have to prove negligence you only have to prove that the defective product caused the accident. Make everyone well aware of this and create a paper trail if you can.
