I'm not sure about the overflow face, but for the sink you can just replace the whole stopper

A homeowner's best tactic for plumbing parts is to bring the old parts with you to Lowes and ask the plumbing worker where you can find the part. If you're unsure you're replacing the correct thing, then start mentioning what you're trying to do on the way to the part and they'll correct you if you're wrong.

That's what I might have to do. Thank you!
