Which posi do I have?

[ABLAZN]

I took the rear differential cover off the Blazer last night to check what gear ratio I had and if it had a posi like I thought. The gears turned out to be 4:56's and it did indeed have a posi. I just am not sure which one it is . It looks like an Eaton, but I am don't know enough to say weather it is the gov-loc or the after market unit. Here is a picture if that helps.

Yep, definitely an Eaton limited slip (aftermarket).

WOW, that was fast, THANKS !!!!!! I was just wondering what gave it away for you, and if these are a good unit. I don't know much about the Eatons since the have only used the Auburns in the past.

Eaton GOOD, G-80/Gov-Bomb BAD.
