Ballast upgrade 2012 Sunsport 22V

Looking to upgrade our factory ballast in our 2012 22V. Anyone know the dimensions of the rear lockers or know what bags we can replace them with to get some more #'s in the boat?

Got it stored away for the winter and am trying to avoid the drive to measure them.

Thanks
Craig

I have the same boat. I’m running wakemakers 850’s in the rear a 360 in the center and 500 sumo sack up front.
