no i did not the car did fine in it's early life with 11 second runs. and healthy horsepowered engines. it won't see that kind of thrashing again. having decades of collision and restoration knowledge and experience, i learned early on not to over engineer.not one less weld and not one more weld. only the same amount of spot welds that the manufacturer put in the car. put a spot weld where there was a spot weld and not to replace it with a stitch weld. if i was building a race car or..... then it might be different. thanks for the concern
