both cocker and phantom springs are nelson springs. I was just being specific that it is a silver phantom spring. That may or may not have a direct cross reference in a nelson spring kit. Mikes springs are a little different strengths than standard nelson.
You can probably also use nelson valve springs. I have never tried it. phantom valve springs are pretty short.
yes CCM ss25.
