Warn M-148 Locking Hubs
 

One of the Warn M-148 locking hubs on my 1972 W-200 is non-functional (won't lock). There is nothing available from Warn in the way of rebuild parts, or a replacement for this eight bolt hub.
Does anyone have any experience rebuilding one of these without the benefit of a parts kit?
And of course, if anyone has an M-148 sitting on a shelf somewhere and could be persuaded to part with it, I would like to know about it.

Thanks...
