Dana 60 / 3:54 / Sure Grip / Worth ?

Can anyone give me an idea what a cut down B-Body Dana 60 / 3:54 Gears / Sure grip might be worth, everything has already been resized to fit into an A-body, do not think anything has been rebuilt on it, good used shape, needing paint and brake job. It is from a B-body, has the two bolt mounting holes for pinion snubber on front of the casing.
