I see some numbers on the outer edge of the ring gear. I'd almost bet that if you look at the numbers they will be Ford. In the thumbnail I was going to say it was a Dana 44, but after looking at it enlarged I think it is an 8.8 Ford, and from the little than can be seen of the external housing it is most likely from a T-bird/Cougar with an IRS.
