As Brad says, the tank most likely no go (and indeed does not fit perfectly over the 02+ airbox anyway)
I would imagine however you could probably make up a bracket arrangement that bolts to the forward frame mount, rather than weld on the tabs per the stock 97-01 arrangement
The complete tail section will fit along with the subframe
You would need subframe, seats, battery box/inner fender and plastics.
The front mountings of the tail bolt into the tank, so those would not be utilized if mating to an 02+ tank
Here's post by member who married the older tail to the 02+ tank - unfortunately picture links are no longer valid.
