D75/25 Yellow top Optima Fits PERFECT!!! I bought it from remy_battery off Ebay for less than 120... I put the yellow connecting piece to the bottom of the battery and stock hold down holds it in GREAT! If you didnt know I bought an optima from Auto Zone they stated one size fits all it ended up being too tall... I have rockford Fosgate terminals! But if you dont want to mess with your battery tray get this one figured I would let everyone know about this!
