Ford 150 OD Transmission install in 31 Roadster

Are the AA bell housings difficult to find? I have heard that they are needed for this application and I hear of so many out there that I wonder where one finds the AA bell housing or is someone reproducing them? I may want to do as Old31 did. I have a 411 gear set and all the bearings. Might be a fun project for winter days when it's raining out here in sunny CA.
