I just got a pair of Superwinch hubs from ebay for my 1991 trooper, and they had an assortment of parts kinda at random thrown in. I was able to buy a set of the snap rings, and the 3/4" washers which fit between the snap rings and the inner hub assembly.... but there was also one larger washer (yes, just one with the pair of hubs...) that I don't know if I need or not.

This washer is 1" inside diameter, 1-5/8" outside diameter, and 2/10ths thick.

I think it goes outside the snap ring, as a spacer?

Does anyone know if this is actually a part of the superwinch hub? and where I can get another one if it's needed?
