[DeTomaso] Techno question: New clutch & slave adjustment

[Charles Engles]

Dear Dave,


               Yes the plunger rod thingee is the threaded rod that connects 
the slave piston to the clutch lever arm.   Since I lengthened it to take 
out the half inch of free play in the slave cylinder (?), I was able to 
actually put the car into gear.   Afterwards, the clutch felt pretty close 
to normal as I recall.

                The master cylinder is original, I think.   The slave is 
new.   No low level of fluid.  No leakage noted.


                Exactly where is the desert are you?


                                      Warmest regards,  Chuck Engles
