Kris, it seems to me from the pics posted that the '02+ has a slightly different bumper. There's no bottom piece on there (that you have) that's preventing you from raising the bumper. The bottom part of your bumper kinda wraps under the frame horns and the bumper support that's attached to the frame horns. '02s and up don't have that and this it's easier to lift up. I'm sure it can still be done.

Anyone got a pic of a '00 or an '01 stock bumper relocation brackets?
