AFB accel pump

Anyone know if the accel pump from an Edelbrock 1400,03,04,05,06 will work in an older Carter AFB, specifically, a Carter AFB #4294 ('67 273). I understand 1407 and up use larger diameter pumps. Correct originals are getting hard to find, and expensive, and buying a whole rebuild kit just for the pump plunger makes no sense to me.
