The bracket was made from a piece of angle iron. It needed modifying though, and I was going to rivet it onto the chassis but I decided to tap a couple of M6 threads and bolt it on. I also drilled and tapped for another earthing point (the middle M6 bold.) Never know when I might need it. I also had to extend the wiring too as the engine loom wires were not long enough for this position.
