CrossfireGal,
In the service manual section 2-12 says about rear camber:

The camber on the rear axle is not adjustable. If substantial deviations in the rear axle camber are found, the cause may be one of the following:
1. Too great a difference in the vehicle level between the right and left-hand sides of the vehicle.
2. Camber strut bent.
3. Accident damage to the frame floor. Level differences at the mounting points for the rear axle carrier between the left and right sides of the body. Experience shows that bending caused by accident also has an effect on the toe.

The service manual does indicate rear camber as -1.13 degrees. It doesn't give a range, so substantial deviations may be hard to define. At any rate, -2.0 degrees sounds pretty close to me for rear camber.
