Positive that the tail lights for 98-00 and 01-02 are different for sedans. the tail lights for the sedans are different size which you will need to replace your whole trunk to make it fit. Too much work in my opinion for tail lights. Just compare the rears off pictures on Google.
And to tell the difference is that the 01-02 has their reverse light and turning lights on the bottom part of the brake light while the 98-00 has their on the top.
