4 wheel disc w/o posi?

Is it possible to have the J65 4 wheel disc option without the G80 posi option. I remember seeing somewhere that with one comes the other, or was I seeing things.

Thanks

Well, I don't konw what the J56 model of rear was, but my car is an 83 TA, and I had a stock 4 wheel disc setup with 3.23 gears and no posi. So I did have 4 wheel disc w/o posi. Food for thought.

The rear in the car is the GT4--3.73. I was just under the impression that like most GM weird stuff, you had to have posi with 4WDB.

Thanks
