I recently replaced the factory stock battery on my 96 4runner with an Optima Blue Top. The new battery is a lot smaller than the one it was replacing and I've noticed that there is a TON of play in the OEM battery tie-down system. Even with the nut screwed down all the way it doesn't even come close to holding the new Optima battery in place. Are there any manufacturers that make an aftermarket tray that would hold an Optima comfortably?
