The battery tray is only 8" long. All of the Optimas are approx. 10". I guess the tray would have to be altered? Which Optima battery would work as I can't find one with the same size.</p>
I guess the corner support bracket could be removed and the battery could hang over. But do you try and match the cranking amps or does getting a larger battery with more cranking amps have any concerns? Optima batteries have CCA somewhere near 700-800 CCA.</p>
