On the '53's the spring steel clip hugs the top of the shaft and sticks up into the rotor. On the '51 there's a hacksaw cut, slanty in the shaft and a piece of bent spring steel is pressed in the crack. I couldn't get one at Napa. I took a section out of another set of points 'spring' and filed it down slightly narrower so it would fit into the rotor better. No pictures tonight.
