t4 master cylinder?

on heritage they list 22.2mm master cylinder as an upgrade - then when you look at part its for 16v mk2 & t4 van…. if you go looking for cylinders for t4 they offer a few variants 22.2mm being the smallest, 25.4 being the largest…
(of which i have somewhere for my t4…)

Question or statement? as im not sure really

I'm using a T4, non ABS master cylinder. Can't remember exactly what size it is. No idea how it performs as I have the rest of car still to rebuild around it.

Didnt know if this was general knowledge and if someone had tried it before

just dug out my old t4 stuff & master cylinder will fit but at an angle no not ideal.
servo is not usable as pin on rear is fixed.
