The hood lines are different, the 02's have about a 1 3/4" taller hood line at the front....so that's a gap to start with....
The widths for the front clips are different too...in short, I think it would be easier to take the pre-'02 hood that already mounts and aligns properly, and modify it to look like what you want it to.
(To me it seems like a lot of work for a cosmetic change, but, its not my truck, and the important thing is it means something to you to make your hood look like a later year's.)
As long as you are starting with a blank canvas...is the 02 the perfect hood, or just better than the pre-02? (You could just design a new style from scratch, and make that, etc.)
