radiator fitment questions

I have a 67 cuda coupe, original slant car. Im putting a small block in it. I got an opportunity to get a radiator from a 72 model 318 dart. Will this radiator be a straight across bolt in to my radiator support or will i need to modify the radiator support to use it.

I dont care about fan shrouds and weather or not its a correct year part, plus i plan on running an electric fan anyways.

Anybody swap these out and know the answer for definite sure before i buy this radiator.

Thanks
Matt
