The original bellhousing will have the wrong bolt pattern. You will need a later, say a 49b up. The next problem is that the 49 up will not have an area to bolt the brake/clutch assembly to. You can make an adapter plate. Several folks on this site have in the past. If this is somthing you are interested in I can provide a few pictures.
