My reply will be,"Don,t forget your bible!
The problem is that if you don't put the back nut on them and the lead has the recess, there is not anything firm that gets held between the front nut and the rail as the metal sleeve is not pressing on the rail and the rubber can give.
Has there been any further movement on this? Back nut will still not fit, but the debate now is back washer or not? Personally, I think the backwasher is needed to provide continuity and support on the back. There is a slight recess still, and if you don't fit back washer is seems a bad job. However, there's a strong thought by some that there should be no back washer as they can somehow vibrate and cause track faults. I don't see how this can be true, otherwise surely the locknut would be loose, and how would a back washer cause additional vibration that the front washer or no back washer at all.
Has anyone heard of a back washer being a cause of fault?
What is official standard now?
