Help - GTA door locks

Hi fellow Alpeeners!

The little bushes on the door lock pin (in the door) on one of my cars are completely knackered.
Simon had some made but Andreas tells me the quality was bad so they are looking for another supplier.
Anybody know where I can get two?
Also - the door self open. Is is actuated by a spring in the lock (I suspect so) or the spring in the door stay?
My driver's door opener is tired, virtually asleep in fact!
Andreas from Simon says the spring in the door stay,, part number 60 01 016 510 is no longer available.
Any thoughts/suggestions would be appreciated.

I have one door hinge inc pin left if it helps:

The spring is in the door itself (middle hinge towards the A post) but I don't have any left I'm afraid.

And there are some priceless details about door mechanisms in the members area from JohnC, including diagnosis, dismantleing and repairs.

Thanks Martin and Simon
Cheers
