Dang!!Rain and cold..Anyways, I ran out and took the measurement. I think when I did the install, I looked at the picture toooo closely which showed the measurement started from the very right edge of the first indentation. When I start from the center of the first indentation, it's off by 4/16" too far and the u-bolt of the bracket is not seated in the indentation of the centerlink. Will re-do after the rain stop. Thank you for pointing that out.
