I'll keep trying unless anyone has a brilliant suggestion.
I would try to remove the spring before disassembling the parallelogram. If you use a needle nose pliers to twist the spring tighter, it will create a gap between it and the aluminum knuckle. Then you can slip in a thin shim of aluminum cut from a Coke can, maybe 1" by 1.5" or just less than the circumference of the spring. Relax the spring. Then pull the shim clockwise to disengage the spring hook from the housing and try gently pulling the spring out. Greasing the outside of the shim may help. A thin exacto knife blade might help with the spring hook.
