2008 Subaru WRX body & structure problems

The clutch pedal on my 2008 impreza wrx feels gritty and makes a loud creaking noise every time it's depressed. When I investigated the noise, I noticed that the entire clutch pedal bracket assembly (attached to the forward firewall) shifts approx 1/4 inch every time the clutch pedal is depressed. I found that the three spot welds securing the clutch pedal bracket to the forward firewall were broken.

The part of the steel body under the dash that supports the clutch pedal shaft assembly fractures into two pieces due to flex forces over time. This results in the clutch master cylinder flexing at its mounting point on the firewall when clutch pedal is depressed. Severed squeaking and noise is heard every time the clutch is depressed as a result. Welding is not feasible as it is located un the dash (above the accelerator pedal) and would cause fire around flammable materials.
