Need 3 x carb-slide duracon washer (part no 92022-1155)

Hi all! 
After several frustrating rounds of chasing a fueling issue, I did a full carb rebuild (literally everything, including diaphragms, cut off valves, etc. Pretty much everything I could think of updating) and in the process, I apparently misplaced the small plastic (Duracon) washers that go on the slides (see attached pics, including one I took from one of Scotch's posts reminding us to not forget them ). I have no idea how I managed it. I do all my carb work in a big tupperware exactly to avoid losing any small bits and pieces, but here we are... 
I can order some from the UK (with a hefty shipping and tariff charge), but figured I might ask here if anyone has any spares (3 needed) laying around they wouldn't mind parting with.
I appreciate you all! This forum has saved my bumbling bacon many a time!
Cheers!
Dan

I'd be tempted to make some out of a plastic milk jug.... 

$3.49 here, from state side... no tariff.

I made a couple of sets from a reed valve from a 2 stroke intake. Worked like a charm. The reed valve material is compatable with the fuel and also, the thickness was within .001" of the original material. 
I remember drilling a smaller hole like 2mm in the reed and opening it up carefully with a tapered burr and then grinding the od to size with a fine stone grinder. Finicky job but in a pinch, it worked.
