I recently chased my mustang a few houses because my e brake didnt engage proper, and i didnt leave in gear

so i looked into the recalls for the car doin some research and sure enough there was a recall for the brake not engaging correctly. well the result of the years of the car and the pressure the cables were under during the rollaway of my vehicle caused the sheetmetal to split where the cables from the park brake go through the vehicle floorboard. thus now my cables are grinding on top of my driveshaft. Ford did the recall by putting some kind of c clamp type mechanism on the park brake but isnt considering the floor as being the fault of the original recall. If the brake worked properly then my floor wouldnt be ripped and my driveshaft wouldnt be grinding(louder with more passengers in car due to weight). I was just needing your opinions if you think ford should consider this as damage due to the faulty ebrake and repair it , or if i should shell out the money for this which is going to be very expensive through ford and drive off broke with no gas money
