The newer Getrag slave pushrod is shorter than earlier slave pushrods because the slave mounts closer to the release arm. The difference in the early and later version master cylinders is in the location of the reservoir and the fluid line connection. How does that length compare to the length of the one you have? The measurement I gave you was of late version.
If you think about it, the master mounts in the same location against the firewall, whether it be early or late version. The pedal has to sit at the same height and travel the same distance. I just don't agree that an adjustable pushrod really does anything since hydraulic systems have no adjustment like the old mechanical cable or rod actuated clutch systems. Ideally the pistons of the slave or master should be near the back end of the bore when at rest. That way they get maximum travel as the clutch disk wears down, without bottoming out in the other end when the pedal is pushed all the way to the floor.
