340 duster 4 speed clutch pedal?

I have a question as in the above post. Number 14 said that I can adjust the pedal to anywhere that I want and then adjust the freeplay every. If the clutch paddle comes up to the rubberebumper , how can I just that any differently... With the clutch paddle resting on the rubber bumper , it is still higher than the brake pedal, Also I was doing research and found that there is different clutch paddle ratio. Assemblies from the slant 6 to the V8. Can anyone explain how I can tell what I have by looking thanks
