I had Jimsvt build me a batt box a while back but the car I meant to put it in never got finished. Well my current car does not need one either so I am going to part with it. It is an extremely stout piece, much stronger than the aluminum one you get from the mail order places. Measurements are 12in wide 9in deep and 10.5in tall. It should fit most batteries. It would also make a great ballast box. $70 takes it home.
