Optima recommends their 75/25.

you can shoehorn the 78/34 in there. but it's a tight fit and touches both an A/C line and the opposite side of the tray. 78 has more power, but the 75 will fit better.

As far as I know the 75/35 is just the 75/25? BCI group 35 batteries and group 25 batteries are the same physical size, they just have the terminals reversed.

Nice, try to get the receipt too for the warranty. 75 is the number that's important to our cars, anyways. It's the smallest of the 3 common side-post sizes. I got a 78/34 for free.99 which is how I know they'll BARELY fit.
