MOPAR Crankshaft's Automatic vs. 4-Speed Transmissions

Sorry to revive this but does anyone know the specs to tell a machine shop how to drill out an auto crank to accept a 4speed? My crank is sitting at the shop right now and I cant find any specifics online. Answers seem to range from, a pilot bushing will work to you need to drill the crank out more.
Buy a new bushing and instruct your machinist to make it fit. He can figure out the interference necessary.
