For what its worth when i ordered the rear I asked many questions about longevity and the strength in both the 9" and the s-60. I was told that while the S-60 is a very good rear, it is hindered by the factory style cast pinion support, whereas the 9" with it's removable center section is available to all types of improvements.

Also because of the pinion sitting deeper in the 9" pretty much both Strange and Moser assured me that there was no comparison of strength when comparing an aftermarket case 9" to a Dana.

really what it cam down to for me is that I don't like working on Dana's at all. The 9" is basically just like the 8 3/4 in overall design and since I was familiar with that and like the way you can set the center section up and the put it in the car it was favorable for what I wanted.

Either way unless you have a way to shorten the housing on the cheap I think you will spend in the ballpark of what a new unit costs.
