Okay folks, I did it. I drilled out a new hole lower and closer to the center of the mount. I screwed it down tight and will let it ride for now. Wife will be happy with her coffee and this time it won't be on a funky angle.
Cheers and thanks for the advice.
I attached a few pics of the cupholder. I tried to show how the original hole mouted too close to the rail and made the holder tilt
