(From my understanding of what rebuildable is...) They're rebuildable. About $15 worth of seals should do it, unless the reservoir is scallopped.... then you either need to resleeve or replace.
When you're putting the cylinder back in, don't forget that the measurement between the bottom of the pedal and floor should be 140mm. It makes it look a bit depressed compared to the brake pedal, but ensures that the piston is pushing in line with the cylinder, thereby stopping and scalloping/gouging that can prematurely end the life of your master cylinder.
And I agree, it is a rather wierd master cylinder setup.....
