RX8 differential Mount fit on NC Differential?

02 Protege 5
A friend broke the differential mount on his 2006 NC Miata at an autocross event 2 hours from home. There is an RX8 in a junkyard and we are wondering if the differential mount from the rx8 will work on the NC. They pull up under different Mazda part numbers but we heard it is because the RX8 one is beefier. Any help is appreciated.
