I have to agree with Steffen here. The c01, c02, .. suffix is the best way to go here.
This thread started with the naming of the valve, and that valve, and three older pneu cylinders, are the only affected parts.
I think they should be renumbered instead of introducing a third way of numbering parts.
Renumber these official files, and create Move to-files.

And this part is still missing from the PT.
It is only present, as a mock-up, in Philo's mpd-file of the MB truck

All other pneu-parts are allready using the c01-suffix for different positions:
4694c01 - c03, Valve
47224c01 - c02, Cylinder
127c01 - c02, Cylinder
2793c01 - c02, Cylinder
335c01 - c02, Cylinder
