jaloi, You will need to know which carrier you have to know for sure. As the gear gets lower [higher number] the pinion gets smaller so 4:56 can be made fit a two series carrier, with the available spacer or "thicker" crown gear. But a two series gear will not fit a four series carrier. If that was originally a 4.56:1 Chevelle you will be needing a carrier. If that was a highway blaster [2.73 or stiffer] car you will be able to do your change. Either way you will have o pull the cover and take a look see. Harry
