Robert, thank you for all the pics and explanations.
My cause for my confusion came from my '13 UCA mount being completely free of the tank, the tank not covering up any part of the mount.
This is of course quite the opposite of what I saw when I worked on my fiancee's '08 GT500
My UCA & mount (pic was taken when I was replacing my driveshaft, can easily see the forward bolt even though I was under the tank):
The fiancee's car (you can kinda see the forward part of the UCA mount sitting above the fuel tank):
I have never seen a mount that has the front bolt totally exposed. Maybe the 2013-up is different?
