Both are 3.8L, and should swap easily in mounts. 98 was the year they switched from 60E to 65E transmission, you may want to swap both as a combo (not sure if you can reflash your 98's computer to work with the 97) in fact I'd swap over the the computer too, and compare the harnesses for differences, exp. regarding sensors and sending units.
