Original E30 M3 part is unavailable so what do owners use now. Cant even find a repair kit.
its 23.81mm originally and not listed since 2018.
just had to do the clutch but there were plenty of alternatives for this but cant see anything for the orig Brake master part number 34312225505

That’s just the E32 750 cylinder and a new line with 10mm connectors to get to the ABS module.

You can get one here for much cheaper still:
