Rear end options.

Come to find out it is indeed a Dana 60 or 9 3/4 as some call it according to the salvage yard manager. Did some research, some of them did come optioned with it: http://www.hemmings.com/hmn/stories/2010/10/01/hmn_feature25.html

I have never seen a 5 lug Dana 60 before.
I did not know Dana 60's were optioned on cars. You learn something new everyday.
However it is a one legged and in dire need of rebuild. I haggled with him he's still stuck on $300 for it.
