A833 overdrive V8 bellhousing?

I have an A833 Overdrive on my 318, I ran into the same issue. ME and my friend swapped the guts from the transmission with the aluminum housing into an iron case. To do this you need to grind off a small part of the part in which the reverse shaft gear goes. After that it was smooth sailing used my same bell housing and have the added strength (and weight :D) of the iron case!
