Kits cover numerous models and have leftover parts. Think Lawn & garden service shop or car racing shops. Extra parts are the kind of things mechanics have a drawer full of.
I myself would probably cut one out of rubber gasket material I have on the shelf. A .44 mag casing to punch the OD and a .22 to punch the ID.

Great information, dedhed. I made my washer out of thin cork (see in left side of pic). Also, I tightened the big nut behind the big black and silver washer thing. That was really all it needed - I should have done that in the first place - Duh!
