I had the chance to measure a '03-'04 next to my '00-'02 bumper. There are a few other measurements I'd like to get in general, but I've modified mine to fit my '95, so I couldn't.
Bumper styling line to bottom of the headlight is the same:
'00-'02
'03-'04
But from that line to the grille was much different
'00-'02
'03-'04
If someone could measure their '00-'02 grille for comparison, that would be awesome!
