Ok, I had to try this. I found an 11mm deep socket that fit perfectly in the spring recess on the shoe and using a hammer I gently tapped on the pins. See picture. It worked, the pins tapped easily into place and the shoe fits flush against the hub.
I am also stretching the springs slightly from 20mm length to 25mm length to see if that helps. I don't really want to grind material off. I'll keep you posted as to the results.
