You mean the running boards?
Structurally, yes... but the plastic body side moldings from 1998/99 to 2000/02 are completely different. It would look like crap and either have gaps or require cutting/shaping to fit the plastic parts on.
To switch over to a 2000 setup, you would need:
Front fender wheel opening moldings
Front door body side moldings
Rear door body side moldings
Rear quarter "dog leg" moldings
Fasteners for a 2000
Blood
Sweat
Tears
It's do-able, but they are different. I have been involved with stretching both a 1998 and a 2000 into limousines. I even have fiberglass molds for the stretched body side moldings.
Short Answer: get 1998s if you're just replacing damaged running boards.
If you're trying to "sexy" up your 'gator, look at 2005-up motorized ones. They can be adapted to your 1998.
