'01-03 Sports and '01-05 Sport Tracs use identical seats, which are different than '95-'01 Explorers. The main difference is the upholstery, both cloth and leather, is unique to the '01-03 Sports and '01-05 Sport Tracs. And the low back seats in some Sports and Sport Tracs were not available in the Explorers. The bases and tracks are the same so the earlier Explorer seats will fit. They just won't match your Sport seats. I swapped seats from '97/98 4 dr Explorers into both my Sport Tracs, '01 and '02, and use seat covers. Straight bolt in swaps. If you have power seats, you might have to change the electrical connectors, so be sure to get the connector and maybe a little wire from the donor Ex.
