Is it possible that some of us may have missed Jerry Mathis' reply to this with a photo of a brand new one?

You are exactly right. If it is bent, it has also already bent the threaded part of the U and that alone could fracture the clevis and cause it to break. I would not get near it until I got a tower crew out there to fix it. I also noticed what looked like a soccer field of something nearby. If that thing falls you guys could be in for a lawsuit should it hurt someone. FIX IT!!

the cross-bolt on a clevis is *NOT *supposed to be bent.
Can you say "run as fast as I can?"
The clevis has been deformed by stress and is close to failure. _*Do not bet your life on this Wink Link!!
