Grainfather G30 kettle pump thrust washers

Hi all, first timer, had a little mishap stripping down pump to clean & check impellor,
front & rear impellor plastic thrust washers flew down the sinkhole never to be seen again,
can anyone supply me with the dimensions of these so that I can make a or procure a new set,
will be eternally grateful if anyone could to a quick pump strip down & measure for me,
pump is a MP-10RN. 6W. Cheers.
