Very True on the size being the same.

If you modify the 6 bolt diaphragm (Corvette and Mopar) by removing the 6 bolt "stem" and swapping on the 3-BBL 4-bolt "stem" then the 6-bolt diaphragm can be made to work with the 3 BBL housing.

The 3-BBL diaphragm has been out of service for many years. It will require a slight change in the stem length (after you grind off the factory peaned end and the stem modified to be re-peaned on the 6 bbl diaphragm), using a lathe).
