Thank - you, I too was looking into the rear posi set-up from an SS. Might be next winter mod. From what I have read thou the 3.91 might be to much gear for our V6 auto. It will take ours out of some of the power band. So I concluded if I get one, I will stick with the 3.73 gearing. There are plenty of threads that talk about the gears, and increased torque, I do not remember the numbers thou.
