I'm sorry, but there's absolutely no way that anybody can find such information on FR24 several days before the flight. The exact aircraft may even be changed on the day of the flight. If there's some problem with the first flight, such as a heavy delay, SAS may choose to just use another airplane.
If I were you, I'd do as Fassy recommended and go via OSL instead. More flights.
