KR1S CALIPER JOINT SEALING WASHERS

[NOSHER]

Hi fellas-think there is an old post on here a few years ago but there was never a reply so I`m posting the same question and hoping someone has the answer.
Does anyone know of a source for the 2 black holed washers that seal the two caliper halves on the kr1s front caliper?
As an alternative I`m considering using nitrile rubber "o" rings so any comments as to whether this would stand up to the braking pressure and seal against the brake fluid ?
