ford 9" 31 spline posi

Does anybody have a 9" 31 spline posi unit for sale? I want the one with the clutches.

I have one, rebuilt with new clutches, from my old 1970 Torino Cobra. It also has new bearings and races. I have maybe 100 miles on it, and then I went to a used Detroit Locker, and now currently a Detroit True Trac. I will take some pics of it, when I go over my Dad's on Sunday. I will see what a good price to sell is as well.

I have Auborn Pro diff. that has maybe 45 passes on it for $200 shipped. May have the bearings to if you let me know what size.

I don't know what size bearing, the rearend came out of a 1980 - 1985 ford truck if that helps.
