Transmission Compatibility question

I currently have a 81 F-350 with the 400 (351M) engine with the OEM 4 speed trans mission. I would like to put a 5 speed manual in it to improve the fuel economy. Is there a 5 speed manual that will fit the bell housing? If not what automatics will fit the engine. Thanks Terry
