sideskirts and rear will fit
but the front end of the 98+ is different than pre98s so you're gonna have to do a lotta modification if you want it to fit
simple way to tell the different between 98+ and pre98s is look at the headlights
there is a group buy going on right now for a pre98 body kit...it is possible that you could buy the front bumper from that and sell the side skirts and back to someone else...or just buy that kit for about $650 + shipping
