Difference In LSD

So I've been looking on the internet and the LSD I bought used is like this:

On ebay

So this isn't the same as a G80... I hope because I'm looking at it's ugly ass right now... I hope I got an LSD that can spin in unison and didnt waste my money..

Thanks,

Bummer, that looks just like the G80 I just installed.

That looks like the G-80 that is in my 2001 silv.. That is not an Eaton POSI an Eaton has clutches and steels in it not a rachet device like the G-80. By an Auburn and just get it over with..
