The only difference b/t the 2000 and 2002 versions is that the tube is shorter. The hood on the newer style is taller. The change makes both of them sit at the same height on the hood.
The pics of the '02 on the www site right are the prototype and have the corners a little wider than the final version though. They will be swapped out soon. Here are some pics of an '02 with the final version of the bumper.
