The winch is a Branden LU-2. It comes with an aluminum housing and is rated at 10,000lbs. It drives off the transmission or, in my case, the transfer case. The PTO has a NAPCO plate riveted to it, not sure if Warn made it or not. You can look through my photo album and see the winch. Start here and you will see it apart as well.
Braden Winch Not to discourage you, but I doubt you will see one of these on Ebay. I have counted 5 or 6 NAPCO's with this winch over the years, mine being one of those. You will also need the shafts, junction, PTO, and engaging brackets to make it work.
You might be able to find one on an old Dodge Powerwagon as they used them too. This site has parts for them.

Good luck
