This really is very silly but I'm looking for a link.
My careless mate removed the nut from the driveshaft (the nut
that you peen to lock) and has lost the washer that sits behind
it (arrowed in the picture).
I can't find the thing so I've been on the web trying to get another.
At the various Ford parts oulets, I can find any number of new hubs.
I also got the peeny nuts on eBay but I can't find said washer anywhere.
The snag is, I don't even know what to call it. Driveshaft washer? Hub nut
washer? Nothing comes up.

So, has anyone got a link to a source? Please let me know if you
have. Eeven a used one would do.

Many thanks, David
