The key is not to struggle. Just let it happen.
Really, just pull the retaining clip with needle nose pliers. Then, push the clutch pedal back and use your flat head screwdriver to pry the pin out. Once you get it started you should be able to pull it all the way out, then carefully remove the assembly.
Verify you like the pedal feel without the spring, then remove the top part of the assembly (so the spring guide isn't dangling).
