Reply to "Effort Reduction Kit"

Ford's reason for this kit was not exactly what one might think. Their Official Reason was so one could sit at a stoplight with the car in gear and the clutch in without tiring one's leg! There is no TSB for replacing a worn-out crankshaft thrust bearing resulting from this poor driving practice... The linkage works like a compound bow-and-arrow: force is INITIALLY HIGHER than original, then drops off to a much lower level as the clutch pedal bottoms.

If you're going to all this trouble, consider adding bronze bushings to all those little mild-steel-on-mild-steel pivots, since they all wear and periodic lubing will be impossible. The wear generates much slop in the clutch linkage over years, limiting disengagement distance and wearing your transmission $ynchros.
