no but when I rebuilt my 78 D44 front it had the earlier style locking nut that is a standard inner nut and a tabbed washer that has notches in the surface and an outer nut that has 4 grub screws that lock into the notches on the tabbed washer much better design than folding over the washer IMHO
here is a similar one on ebay to give you a better picture then my description
