D1 Rovertym front bumper will work on the ‘03/04 DII with only a couple modifications. One of the mounting tabs on each side needs to be trimmed by about 3”. The D1 bumper “returns” too far back into the wheelwell of the DII (DII has larger wheel wells), so it was necessary to trim about 2” off of each of these returns. I have mine from my '96 mounted on my '04 now.
