Warn hub identification

Does anyone know the difference between various early model Warn locking hubs? For example the M2, WL2, WL2A etc? What years were they made and for what vehicles? Is there a specific type that I should look for to be period correct on a 63 CJ6?

 

Jeeze, no one knows the history for the different models of Warn hubs? I'm suprised. Someone, anyone Bueller??

 

Some info here Warn Hubs Not a lot, but some. Even Warn doesn't have much.

 

I've found some info here:

I believe this is a copy of Willys lit, sales and accessories.http://www.vintagejeepparts.com/jeep_legend_accessories.asp They list 2 models that were "factory approved". The manual style WL-2 is most commonly found and would be period correct.

 

I have a '63 CJ6 and my locking hubs are AVM spring manuals. They are probably not original, but who knows. It is just food for thought.

 

AVM was not making locking hubs in '63 so no, not period correct

 

drive flanges would be period correct.

 

My '66 CJ5 has Lock_O_Matics and I believe that they're original. It was a special order vehicle and also includes a 4 sp tranny and a rear PTO so the Lock_O_Matics may have also been a special order item.
