12v Battery Mount

I apologize if this has been posted recently, as I see a ton of 12v battery posts, but I could not find an answer on this.

I recently replaced the 12v on my own (not through the dealership), and I got group size 47, as most threads recommended. But the battery dimensions are slightly larger length-wise. The OEM bracket no longer fits - it is maybe a centimeter or so to big for the new battery.

Has anyone had this issue? How did you resolve it? Can anyone recommend a good aftermarket bracket or battery tie down?
