pictures of pedal assemblies 340 vs. others

Its the measurement from the pedal pivot to the push rod pin that really matters, the distance from the assist spring pin the push rod pin really doesn't matter unless your trying to identify a pedal setup from a 340 car. Obviously the greater the distance between the pedal pivot and the push rod pin the more travel you'll get at the push rod, this also increases effort thus the need for the heavier assist spring to keep people from whining about too heavy of a clutch. Also it seems like some cheap part store 3 finger pressure plates dont have the finger hight adjusted right, this will cause disengagement problems and clutch chatter.
