Hey folks,

I have an old and very battered Sinn U2 that has been through the wars.
I'm currently in the midst of sorting it out on a learn as I go basis.

Anyway next jobs are to replace the corroded date disc and to fix the sloppy bezel.
I know Sinn changed from a spring loaded bearing system to a full click spring setup a couple of years ago and as I'm missing a bearing or 2...
Before I go ordering parts and snipping spring bars for the springs.

Is the 60click spring available to buy anywhere?
Is there a substitute that will fit?i.e is it a generic part?
Or do I need to drop Sinn an email?

Any steer will be very appreciated.
