Bumper bracket?

I hope someone can help me with this question. I am converting my front trim to the wide 911S type without the front bumper guards. my question is, is it necessary to use another bolt in place of the one that went through the inside bumper bracket (the one the went into the bumper guard. Without it only the bottom hole on where the bracket attaches to the bumper will have a bolt holding the bracket on. Is this O.K.?
