I can’t get a grip on which master cylinder I have on my car. It appears to be original but who knows. The replacement I bought a long time ago appears to be the wrong one (smaller nose diameter-not sure on internal diameter) and is also missing the little lock bolt hole that my current one has (in the second pic next to the circlip).
So a ‘72 3.0 is supposed to have the larger or smaller diameter cylinder? Part numbers:
34311103271 is 23.81mm
34311120832 is 23.81mm
34311120479 is 22.20mm
I think I remember reading that the 2800cs had the larger diameter cyl because it used the thinner booster?
If I am reading this correctly mine measures 23.72 so clearly the larger one (I measured the diameter of one of the internal metal pieces).
I’d like to rebuild this but don’t want to buy the wrong kit or if that doesn’t work another wrong complete master.
