Fender emblem holes

Just out of curiosity, have you looked at the back of the fender to verify that they have been welded shut? Many times you find that they are just filled with filler and you can get a sharp awl or other small wire or drill and open the holes back up. Even if they were welded, I doubt seriously that the back side was finished smooth and that you can find that original holes quite easily and drill them back out. Just food for thought.
