Sadly, I have everything apart from that washer. I think any washer roughly the right size should work ok, given that it is an index lever rather than friction.
What mech are you planning to use? The 7 (and 6) speed index rings work in the standard pull levers with the old rear mechs (Super/Nuovo Record, Nuovo Gran Sport, early Athena/Chorus/Record), but not with the 8 speed rear mechs, which are set up to work with the 'long pull' levers. I've only tried the latter with the 8 speed index rings.

I'm hoping to get it to work with my Athena rear mech, believed 7 speed as I have tried the long pull 8 speed levers on everything and got no where...so may become available.
