If you care about handling, the amc15 axle is about 100 lbs lighter than the amc20. That's a lot of unspring weight, in the rear of a car with a light rear end to begin with. I don't think there's a twin-grip amc15 (others may have facts), but they're cheap and plentiful. You'll need a shorter driveshaft with the big axle; the rear "U" is closer to the front of the car.
