Bracing shock towers?

all those spot welds have held together for 40 some years and not had a problem until the inner fenders were removed,what would be so bad about plating a spot on the fire wall cowl area and adding a tubular support from there to the shock towers and down to the frame,you can take a car that runs a ten second 1/4 mile and add 500 lbs of roll cage to it and change nothing else and the car will be faster and safer and even if it goes slower that can be fixed,what if it isnt safe enough?can ya fix that??????? my .02
