Help me identify this LSD/Locker -- Discovered it is a LS (1 Viewer)

[Willard]

I bought a full floating axle from a member here. It was out of a 60 series in AU. When I got it, it had a "Use LSD oil only" sticker on it.
Rebuilding it this weekend I decided as my 3rd was just rebuilt and I am not ready for 4:10 gears (I have a set on the shelf) I would pull the third and replace it with mine.
Upon pulling it I was surprised to see below. What is it? I cannot see any springs and there are no holes for air, electrical connections on the third.

Found out it is a LS. So now the question comes down should I keep it and rebuild it or??

probably oem lsd.
not sure if parts are still available for them or not. even if they are still serviceable, not likely dealerships here will be able to get parts.

If it was in the front axle probably have a lot fewer miles and less wear than the rear axles. These have springs and clutch pads that wear. Would go thru it before installing it.
