I'm wondering if someone can help me out. I had my differentials rebuilt on my 1970 FJ40. I had a limited slip differential added to the rear and all new bearings and gaskets. When I got my diffs back the breather valves weren't attached. I am assuming the two shorter ones go in the rear and the longer one goes on the front? Not sure why one is longer than the other two. Any input on this would be helpful. Thanks!
