Old lady clutch pedal

Has anyone modified there clutch pedal ? From the 5 1/4 inch old lady pedal throw to the 6 inch throw? If so do you leave the over the top spring off or put it back on ? I have a center force clutch. Rite now at 5 1/4 I'm not getting the clutch to disengage with pedal to the floor unless I adjust the throw out bearing against the clutch fingers. If I adjust it back away from the clutch fingers can't get trans to go into gear. So I'm hoping that the mod will help . In the pic you can see its 5 1/4 and I will extend it to 6 inch will put up more pics after the mod . I'm running 440 scatters shield and A833 overdrive . With big block a body z bar
