I believe the 2,3,4's had a return spring on the slave cylinder. This would
cause the SS piston to return to its 'home' position wherever that was. The
adjustable push rod was needed to maintain proper clearance between the TO
bearing and PP. The rods on the 6 just sort of float out there and clearance
between PP and TO is minimal. Adjustable rod on the 6 will make no difference
unless a return spring is attached to the clutch release arm as in TR4. At
least that's how I remember it and the more time that goes by the bigger the
memory ? becomes.
