You'll need the grille from a 98 200SX. I have a 98 200SX SE and when I installed the Nis-Knacks projectors on my car, my stock grille was sticking out. If I can find the old pics of my car, I can post them if you like. Since then, I've replaced my stock grille with an Erebuni one. So I think if you buy the 98 200SX headlights, the headlights might stick out a little unless you get the grille also.
Also to avoid confusion, see if I got this info right:
98 200SX = 99 Sentra (headlights and front bumper)
97 200SX = 98 Sentra (headlights and front bumper)
