Is a 1972 6 cylinder PS pump same as a V8 pump

I have a 1973 Dart and a 1972 Demon. the dart has a 318 and the demon has a 6 cyl. My darts power steering went out and i had one off a 68 charger it looked aftermarket because it seemed 100% different and the bolt holes didn’t line up to it so i have a 72 6 cyl pump in storage and i was curious if it would be the same if i need to change the brackets or what before i try to pull it out of storage
