Terry, I think you're looking for something that doesn't exist. There are
only three pieces of rubber in the MC, the seal for the 'foot' valve, the
seal for the main piston, and the rubber dust cover.
I'm not entirely sure what steel cup you're talking about, but the only
piece I can think of is kept from touching the cylinder wall by virtue of
being mounted on the piston.
