Need Help figuring out what bell housing to get

I also have the cast iron OD box. Still can't locate a bell for mine. Without buying new that is. I have 3.91 sure grip in my duster. Long ways from being on the road in that car though. .060 over 318 and speed master heads stock bottom end. We will see when the time comes how the combo is for cruising then I'll decide which direction the car goes after a summer of cruising weather I pull it back apart and back a mild street strip car out of it with a different gearbox. I'm torn reading so many mixed reviews on the OD Bruce Jenner.
