I worked on my front clip today and found that both diagonal braces were broken. I didnt even know it until I started taking things apart. My question is: Are these things even necessary? There must have been some stress on them because they were broken. How do you get behind the rivets- by taking the radiator out, I suppose? Can I use other holes? Is there another way to fix it? Can I leave the braces off and not worry about it? They are kind of flimsy looking but Im guessing that they wouldnt be there if they werent needed. Right?
