I don't know how original you care yours looks.
65 coronet and I switched to an aluminum dual pass rad from 4 seconds flat.

the tanks are on the sides instead of top to bottom. got the 26 inch rad dimensions, so it bolted up where I put the 26 inch in my car. but because the tanks are side to side, less of it is wasted on the smaller opening for the 22 inch.

had to move the horns though to the outside of the rad support, but don't remember if that was the reason why.

there is no trans cooler though, and both entry and exit are on the same side.
they make a 3 pass so you can get them on opposite sides if you need it.
