i took the bottom pin out completely, but the assembly won't budge and i can't access the stock spring at all.... here is a picture of what i'm dealing with now... i can't get the bottom part to detach at all

 

Grab it with pliers and yank it out.

 

Try pressing the clutch pedal in, the spring should be able to move and you'll be able to pull the bottom assembly out just by pulling on it.

Be careful, if you dont push the clutch pedal in and you try pulling the bottom out the spring will have a little tension.

Wow! How'd you get the pin out without unloading the pedal? When unloaded, it's easy to remove without tools.

If you decide to try to remove it while loaded, PLEASE WEAR SAFETY GLASSES!!!!
