Anybody else having problems with stress cracks behind the rear seat? I have a 1993 T-Bird and about a year ago I had on both sides behind the back seat about 9 inches up and about an1-1/2 from the wheel wells a crack on each side about 2 inches long. I drilled a hole on each end to stop the spreading of the crack and filled it in with seam sealer. About a year ago the brace that is behind the rear seat broke at the top on both ends. I reinforced it with 1/8 inch metal and about a week ago I noticed a noise. I checked it out and behind the rear seat where that brace comes down in the center and bolts to a bracket tack welded to the body broke loose. Now I have to get someone to weld it. Anybody have this problem and any ideas to stop this from happening. You can really fill the car twist when going over bumps like speed bumps. Oen to any input.
