Hemi - 5speed - hydr clutch system

Hi,
this less Hemi related. I know. But I know as well that here is the best tech ;-)

Currently I have the attached master/slave installation in the Dart. Unfortunately it is not serviceable, means all pressed together plastic cylinders and line. This set is out of a 96 Dodge Dakota, V6. I have the 5 speed from a Toyota Supra installed.

Now the master is sucking air.
And replacing with the same plastic stuff is ...

a) very expensive in Germany because not to get that easy, impossible

b) What I'm looking for is a similar set but serviceable. With bleeder screws ..... Any idea?
