They look so close dont they! the spools of 120 and 220 are slightly larger than the 620. It might be becuase the older ones were usually metal and the newer 120/220 are plastic. Are you trying to fit a 120 spool into a 620 spot? If that is the case in the past with my left over 120 spools is grind them down on a belt sander until they fit. You need to be careful so that they dont melt or anything like that. Then i would take the film into the darkroom and re-roll the 120 onto the altered spools... i had to do it in the light a couple of times before I could do it in the dark.
i must say that i've had success with this and it was worth all of the work sanding and re-rolling to use the camera I wanted.
try it out and see what you think.
