So I had a small plastic piece break off inside the bail spring housing. The piece that broke is molded into the rotor. I got a replacement, but I'm having a hell of a time removing the existing rotor because I can't get the spool shaft bushing off (412-1). I removed the c clip but there seems to be a larger diameter thread at the bottom of the shaft locking the spool bushing on. There is a keyway pin underneath but that has slop in it and not impeding anything. I could use some help with this one.
