I remember seeing that, too. It was angle cut on the rear with that end welded to the top of the bucket so as to come out relatively parallel to the ground when the bucket was in the 'dump' position.
If you want to do that on yours the only halfway tough part would be getting the angle cut that you want. For that, just park on a level surface and put your bucket wherever you want it to be when your receiver is parallel to the ground. Place a level on the receiver tube to get the proper angle then mark on side of the tube with a protractor and cut along the line then weld it on. Just make sure you don't take so much off the back you can't line up your holes with your insert without trimming it, too. /forums/images/graemlins/smile.gif I might suggest cutting from one edge across so you just remove a triangular piece (when viewed from the side) as opposed to taking off a larger, four sided chunk.
