Best radiator for 67 dart with 360

I've had both a Champion and a Cold Case. I like the Cold Case better for looks and it dropped in. I had to slot the Champion but I think this was before they made a more dedicated radiator. The down side tot he Cold Case I think the new Champion is the space the shroud out, so you have to fill the gaps top and bottom. I riveted on garage door seal to fill the voids top and bottom.
