Slant six/V8 radiator question

I need to replace the rad in my '66 Barracuda with the 273 engine. I saw two cars that MIGHT have the rad that I need, but I need to be sure. one car is a '65 Canadian Valiant with a 225, and the other is a 70's Aspen with probably a 360. I could take a 15 minute drive out to the wrecker's with the old one and match it up, or maybe send them a pic of what I have, but I thought I would ask here if mine would match up with either car before I do that. Thanks.
