Asking $500obo. I pulled this out of my car about 1.5 years ago, and don't see ever needing it again. I used it for 2 years before I pulled it, and everything worked flawlessly even while planting 400rwhp through drag radials. It does need drum brakes put back on as I put them on my dana. The stock drum brakes from another 3rd gen fbody will bolt right back on. The positrax posi isn't installed right now as the axles need to be pulled out to reinstall the brakes, but I will include it with the original directions that are easy to follow and don't require any special tools or knowledge. Now the pics:
