I had to move my battery location from drivers floorboard to firewall, mainly because of headers and brake master cylinder in the way. I got this solid heavy aluminum tray from Speedway, you just have to bolt it thru the firewall with long bolts or all thread, nuts and washers. It worked out perfect! Very strong and hood closes just fine. This tray was $40.00 but they have many different ones to choose. You can also find all kinds of battery trays on Ebay. There is no kit that I know of, just make one!
