I actually did all of that before trying here. Saab UK are useless, none of the seven "Dealers" had a clue from the VIN No. or the door plate numbering, which is the part that is supposed to identify the suspension. Seems only option that might yield a result is from Saab Sweden.
I'll leave the rating as it seems you have hit the same brick wall as I have. This is all because I am in dispute with a garage that have just fitted new front springs, which have the front end sitting higher than the back, the space between the Tyre and arch used to be almost none existent, now I can put in my clenched fist and move it up and down. Mind you the ride is much less harsh than before, but the end of the spring is 180 degrees away from the stop in the bottom cup and creaks as I'm steering, then jumps with a "boing" noise when on full lock. both sides are identical.
It's resolved thanks, I finally got the answer from Saab Sweden, the car was factory fitted with the sport suspension pack.
Seems the Arc version had standard springs, the linear can have standard or sport as an option, the Vector Sport has sport springs, the Aero has the same sport springs as the Vector with an option of a set 10mm even lower.
Saab part No -93190595
So on Tuesday I'm getting the correct springs plus new upper bearings fitted for just the cost of the bearings, £UK 46 Bilesteien made.
Thanks for your help and I hope my babble above may be useful to you in the future.
