rear end question

Bruce,
I was reading some in teh Moparts link you sent me and I have a question?
on the 8 3/4 Axle end play and adjuster lock page it talks about a right side axle retainer should have a threaded adjuster on it held locked in place with a finger type retainer attached t one of retainer bolts. I did not have anything like this on mine when I took my axles out the other day. Do you know anything about this?
