I picked up three of the four to measure for future reference.

.. Material=Aluminum with what seems to be felt on both sides
.. Thickness=0.067" & 0.066"
.. OD=0.826" & 0.825"
.. ID=0.487" & 0.488"

But the dealer didn't have the differential crush washer in stock.

I don't know the answer to the size question.

What I know is that the front differential drain plug washer is copper and
a different size than the other three differential washers.

The front differential fill plug crushwasher is aluminum, and is the same
part number as the rear differential fill and drain plug crushwashers.

So what you need are two different part numbers of two different materials.

Front/Rear differential fill & rear differential drain plug crush washer:
.. PN=?
.. Material=Aluminum
.. Thickness=?
.. OD=?
.. ID=?

Front differential drain plug crush washer:
.. PN=?
.. Material=Copper
.. Thickness=?
.. OD=?
.. ID=?

No, but when I was changing oil on my Subaru and could not find washers
I just bought a bunch from the dealer. Figure dealer's prices are
highest but its only a washer. I would not buy my cabin air filters
there as they were $25 cheaper elsewhere.
