Door switch and clutch master cylinder "piece"

Sorry for my poor description but I'm after a couple parts, One is the driver side black plastic door switch it swivels I think it tells when the door is open or closed. I believe it has an "R" on it stating that it's for the right hand side.



I'm also after a part I don't know what it's called but if you look under the clutch pedal there is a metal "barrel" that cusions the rod that goes into the master cylinder. I just replaced my master cylinder 2 months ago and now that barrel is busted so I don't want to replace the whole master cylinder just that barrel.
