Are you sure that is an original battery tray? I never seen one like that one. The original setup I know of had two hold down rods and a wire bracket on top. Fusick sells the top and hold down rods but not the tray. The hold down is part number HD6117 and the hold down rod they sell is HDB005. They show it takes two of this rod but I think it only takes one and they don’t offer the other style. I can’t remember now if it takes two of this rod or one of two different styles?
