Hi Guys,
I finally got around to having some replacement hub washers made.
I got the *&%$ with only being able to buy the whole kit (nut, washer, cage). However Motorsport tools in the UK do sell just the washer.
These have been laser cut using a new OEM washer as a template. They are 3mm thick (OEM ~2.5mm).
They cost $1.50 each so am happy to do for that (plus postage) for forum people
Mark.
