I don't recommend doing it without a donor car. The entire 97-99 system can be made to work and almost no modification to the car'* body is needed but the wiring is time consuming and requires a lot of thought and concentration.
Fuel tank is the same except 98-99 which had a recess for the tank pressure sensor. The fuel lines are different, it helps to have the 97-99 lines and sending unit so there isn't any cutting and splicing.
the A/c system should interchange.
But if done right...(note the donor 99 car in the window)
.....You can have an unusual ride.
