You’ve been told by whom? Look it up yourself? I can almost guarantee you it’ll be a group 35. They will likely list 490cc amps for all engines as well.I've been told group 24 and 34 as well.. I think I have to measure and see what will fit. There is no room for anything larger than what is in there now. And there isn't a group number on the currant battery, that would just make it too easy.
