Is an 8 1/4", 2.45:1 diff housing exclusive?

In an earlier post I called the ring-gear carrier, a case. To me they are the same...... but I guess I was wrong. So from no on I will use carrier.

Hope you didn't take my highlighting carrier and housing as busting your chops. It wasn't pointed at anyone, I was just trying to make sure what I was saying was clear. Saw plenty of posts in the other thread where it seemed like people read through it and then commented and seemed like they got lost on which was which.

I could have use the term case as well for the carrier, just seemed like "carrier" was a little more clear and I was working hard to make sure I was as clear as I could be.
