In '97 the Imprezas got the new nose with the different hood/grille/headlamp profile. An RS hood is a bolt-on for these. With a '96 and earlier car you need to change the lamps and grille for it all to work.
The ass-end of the car is the same, regardless of year.
If you want a lightweight car for a donor find one without sunroof or power windows. Makes a big difference.
