Mine has a similar problem. The arm to the check is connected, but however it attaches to the inside of the body is loose. I was thinking of cutting a square hole maybe 4 inches by 4 inches on the inside of the car right where it looks like it attaches to the body, with a cut-off wheel or something. Then you could get a mig welder in there and just weld the arm more solidly to the body....from the inside.
