LC rotor differences?

[nokturnal]

Do the numbers on the LC rotors mean anything to the home mechanic? Do they all interchange?

I know the ypvs flywheels can be problematic to mix.

I have one that is in need of replacement. The one available visibly is the same, but the stampings are different...

There has only been one part number, so all are the same. 4L0-81450-50

Thanks for that
