70 Swinger over center clutch spring
The spring is easy to remove or install, but, you have to be willing to remove the front seat, steering column and the pedal structure/frame. I can do the spring in a few seconds, either way. It really doesn't take that long to do all of it. How much time did you spend your way? The spring can hurt you trying to pry or stretch it, how do I know this? I am not trying to poke you in the eye, but this question seems to come up often. Wish that I could make a video, others have figured it out too.
Glad that you got it out!
