I've seen another thread or two about this but mine is a little different. (so am I according to my wife) All it takes is angle iron and a drill to make. The welding on the angle wouldn't have been necessary if I had wider angle, I had to add a piece to make it tall enough. I used 3 bolts on each piece to anchor to the bucket. The back of the angle ends where the back of the bucket bends upward, which is where most of the force is absorbed. This puts it just on the other side where it attaches to the loader, which is where God and the japanese intended for it to be.
Top is attached to my added on hook with chain as shown. Works GREAT!!!
