I am posting this here and maybe it can become a sticky since there seems to be a number of people looking for the O rings for their early Warn locking hubs. There was a guy (Winston) over on the OldWillysForum who found a guy (Jessie) who custom made the outer hub knob O ring as it has a special angle edge. This O ring goes around the brass knob that you spin to lock/unlock the hubs. He also has the inner O ring and has a complete kit which includes the bearings, bolts, etc. These just became available this past summer (2018). I got a set of the O rings only and put them in one of my pairs of hubs I'm rebuilding. So far so good. I did not need the other parts so I cannot speak for them. My hubs are the 3 ring but it is my understanding that they work for the 5 ring hubs also and possibly for the Lock-O-Matics, but that will need to be confirmed. The company is TorqueKing 4x4 out of Billings MT. This is not intended as any sort of advertising, but simply as a solution for those trying to keep their vintage hubs going. Winston on the OldWillysForum site did a lot of leg work chasing to make this happen so he deserves credit. These are reasonably priced too, given the fact that they are now available and weren't for years. The O rings are: Outer hub dial O ring for vintage Warn QWU15095 Inner O ring QU30075 Hope this helps others.
