          Found the diaphram.but not the four screws. Anybody have some, or their measurements? Looks like they aren't available anymore.

            I have my old front master cyl from 1980 xs1100S,
            the plastic reservoir was bad looking so i put on a nissin radial (over kill) unit, so i SHOULD have those parts,
            Best i remember the screws looked a bit rough but i can soda blast them. I work at a bike shop, have some parts, etc Here in west texas
