AMC 20: Open or Trac-Lok

I have taken the differential cover off and im not sure it i have the open or trac-lok. Can someone post a picture of the two so i can see the difference. I have a 79 CJ5 and it has the AMC 20 narrow axle. I have lifted the rear up and turned one wheel, both spun the same direction. But i put it in gear with the jeep on and i was able to stop one of the tires while the other continued to spin. I want to make sure i dont have the true-lok before buying an Aussie locker for it.

Does anyone have anything they dont like about the Aussie locker for the AMC 20?

The Trac Lok has squared shoulders on the carrier while the open unit is rounded.
