It is also 5 inches deep. I need it in black. Looked around the web could not find it. Thought I would try this route before doing the real hard research.
A fairly easy fix, and may be a lifetime fix, is to put a support on the bottom of the box. A piece of 6" wide steel plate, about 1/8" thick, about 18" long. Drill a couple holes in the ends, outside of where the box would sit on it.
Place the support over the top of the battery box and center it so the holes you drilled are equal distance from the edge of the box itself. Drill holes for 1/4" Bolts (carriage type preferred) long enough to reach down below the battery box and through the support plate you just made. Put a piece of old innertube on the plate and slip it over bolts you have installed. Secure with "Nylon Locking Nuts" and pull support plate up against bottom of battery box until the bolts are supporting most of the battery weight.
The battery will never go anywhere and the stress on the flanges will be near nothing with the support bolts. When finished installing, cut excess bolt threads off so they don't get in the way when working underneath.
