After 20 years a P6 again finally a V8 automatic. With work that is.....

So paint is ready so I can put anything back!

the brakeservo looked a bit sad now the sills are nice black so took it of the cilinder and blasted it:

off course the gasket is not available on its own only in an expensive rebuild kit as far as aI could find on the internet.
But you can make your own off course. Tak a piece of gasket paper(?) is that proper English? make the holes and with a hammer you canb easily "cut" your gasket.
