I have read many have removed the clutch height adjuster because it caused adjustment problems and cruise control switch problems.
I test drove my new firewall adjuster---not much change and I cant see where a new quadrant will make much difference, but I ordered one anyway.
Ford came out with this antiquated clutch cable system (No quadrant) in the late 60s, the old mechanical linkage system worked better. I wonder if the current hydraulic conversions would work better or a different aftermarket pressure plate? Ive been a standard stick shift kind of guy for many years but I hate this cable system and the Tremec, If there was a complete Auto trans conversion including computer , shifter and console i would switch yesterday!!!
