[Wiesner Ralf <Ralf.Wiesner@at.siemens.de>]

Hi everybody,

for i cannot get any parts of the cardan shaft seperatly 
(new on is 500$). i search for rubber-bearing in the middle of
the cardan shaft that is connected to the car himself.
Does anybody know a way to get it without buying an new c.s.?
   
thanks
