Identify This Rear End

This differential was in the trunk of my 73 Polara Police car. It has the Mopar 5x4.5 bolt pattern but I don't know what it is. Anybody?

The pictured axle is a 9-1/4" axle. It is a late build 1976 or 1977 and later car axle, if the cover is original to the unit.

Thanks. All the pictures I found showed the 9.25 cover was flat top and bottom while mine is only flat on the bottom. Must be a certain years thing.
