Over center spring

large washer trick works if you can find enough of them. Install them with the pedal all the way out. When press the pedal in with washers in place, it should give you enough play to remove it

I may be wrong but I did the washer thing. If you disconnect the rod at the pedal then push it will go to the floor and stay there (I think lol) then stuff it full of washers and pull it back ? it's been a while but I did it by myself .My memory sucks ! lol
