thanks

You have the same bellhousing I do. It is a 11 inch truck bellhousing. You will need a bushing for your Muncie because the opening is larger, something like 5 3/8 inches and the Muncie is 4 7/8 ( not exact measurements ) There is someone on this board that sells the bushing. I purchased mine from Novak Industries part# BR4

You are welcome !!

The Muncie bell is 4 5/8.
