By these pictures Link does this look like a trac-lok third member? I have my differential out and apart and it is supposed to be an Open 3.0 but looking at these pictures it looks exactly the same. Wouldn't a open and a trac-lok third member look different?
Thanks for the reply. After reading your reply I took a better look at my third member and do see the difference between the two, there's more metal behind the ring gear of the trac-lok then on mine. Thanks again.
The one in the link is definately a traction-lok. Here's a pic of a 9" open. Notice the bolts holding the 2 halves of the carrier and how, like the others have said, they are not recessed and you could easily put a box end wrench on them.
