I can't speak for the fit on a Bomber ('65/'66/'67) as I've never owned one and only worked on the bottom end of one with my drag bike decades ago (and it didn't use the alternator), but I know all the later stators are the same. I believe a newer model would fit but I can't be sure. did you go to cmsnl.com and look up a 4 speed version and the 5 speed version to compare part numbers? That should tell the story
