Hello
First excuse my awful language, I am best in French...
for my 1975 2.0 L from california,
I look for an Adjusting gear for internal pistons for rear brakes (view photo)
I have only one... and I have 2 brakes !!! And it is not possible to find it here in France. And Porsche dealer can't help me if I have no number of this part...
Perhaps have you this little part in spare, so mail me.
You will be very sympatic
