I would advise not using the thick stock bumper/seals if you have changed the OE 1 1/16" master cylinder to a smaller bore (like a Mustang 1" during a brake upgrade) because longer pedal travel will be needed to assure fully stroking the new master. Much thinner rubber pads can be used as bumpers, and floor padding and carpet should provide enough sealing, and is what was done on my '40.
