What is the pedal you started with from?
It sounds like maybe you need to swap to a OEM S10 pedal and duplicate the master mount location. Shame about the paint

FWIW, my '95 Sonoma with factory master pushing an internal slave into LS truck pressure plate works fine, nice light pedal. They changed clutch master location between 1st and 2nd gen s10s so they must have also changed pedal setup. Yours looks a lot like the master setup on 3rd gen Camaro. My son's LS swapped '91 Z28 using factory 3rd gen pedals & master, with a t56 and internal slave has a very heavy clutch pedal as well.
