They are both used. The posi has had the cones turned and re-shimmed. It works great in a straight line but will still spin the inside tire during turns sometimes. The 3.27 gears are factory gears and worked great when removed. I am asking $150 for the posi unit and $75 for the gears or $200 for both. Shipping is extra but I will only charge actuall cost. PM me if interested.
