This involved some welding. Had two different trays, none which would fit inside the narrow space between chassis and intake manifold, so I made my own. It fits very nicely, all done by scrap iron found on the property. The battery is a brand new 80Ah el cheapo battery.
Here’s the space before
Freshly painted
Please note this is the sport edition of battery trays, as you can see no excess weight exists in this tray with all the holes in it.
