Just FYI- the '99+ are still steel [emoji1360] Similar flat plate risers could be made to work on those, but the holes are not as close, so the plate would be quite a bit bigger. Might not look pretty, but I suppose it would work. That being said, you can actually mount the '99+ bumpers the same as the pre-'99- the same holes are in the frame horns. You need to drill a hole in each bumper bracket, but that's it....on the early steel bumper models anyway...
