introduction; greetings to all

Hello my name is Patrick. This year in april, I went to the Pate automotive swap meet in Dallas. I purchased a 1972 Duster that had a decent 73 block 318. This is the mid-life crisis I was hoping to avoid. I came to these forums to gain some more knowledge about Mopars in general. My question is this; will 1975-76 8.25 rear axles fit into a 1972 8.25 rear end? I am hoping the only dimensional difference is the lug stud centerline and consequently the 10 inch drums.
