Clutch master cylinder rebuild

[Pyral]

I purchased a brand new clutch master cylinder (cmc) because the reservoir on my old one would vibrate noticeably against the metal base when engine braking. But my old cmc worked perfectly and I only purchased a new one because I don’t know how long they’ll be available.

Is it possible to get replacements for the plastic parts so I can keep it as a backup?

You can get rebuild stuff from Toyota at a minimum. But I don’t think there’s much risk of discontinuation of primary chassis parts like this from Aisin. I’m about to get Aisin clutch hydraulics for my 88 and they are in stock still.
