Purchased the Odessey PC545 battery with metal jacket so I could fab my own battery box. The battery is RTV into the box but can be removed by sliding a 6" SS rulers down between battery and box to cut and release battery. Made side brackets from 3/4" alum angle and riveted to battery box sides. Riveted battery box to firewall cross supports and angles to firewall with alum backup plates. Pic 3.
