where am I going wrong?

Any tricks to getting the over spring off?, I tried for over a half hour last night with a pry bar and screw driver with no luck, I got a hold off a pretty cool Snap-On short prying bar with a fork in the end and a sharp bend that might work I could try tonight, it seems a pry bar is too long to work with in the tight space its in and I really don't want to take the pedals out or cut it.
