Ah no, I won't need to move the location, it's the battery terminal size I'm talking about. The jap import batteries have narrow terminals. I found out the hard way when I went to a brake/tyre/battery place to get it changed. They didn't stock them, but recommended going to Southside Automotive for it instead.
That's why if I was going to get a bigger batter, I'd probably have to change the terminals too, as well as the bracket.
