is there anyway to make a 97 cavalier body kit fit on a2002 sunfire?? if so what all needs to be done

You could use the front part of a Cavalier body kit, but you would have to get a Cavalier hood, fenders, headlights, marker lights, bumper cover, crush guard and splash shields for it to work and for everything to fit properly. The sides from a Cavalier body kit will work without doing anything. The rear part of a Cavalier body kit would not be able to be used without a ton of custom fabrication. The rear ends are completely different.
