74 charger engine trouble

[Roadkill74 SE]

I got a free 400Ci engine that I removed from a 74 Chrysler newport that I want to put in my 74 charger SE that originally had a 400Ci engine in it but the Chrysler engine doesn't want to go in right. when the motor mounts line up the oil pan doesn't and when the oilpan goes in the mounts don't line up. should i get a new oil pan or new motor mounts

Check to see if the 2 oil pans are the same.  If they are different, then try using the one from the Charger on the new engine.
