I would not purchase a new radiator without making 100% certain it had at least the same number of tubes and fins-per-inch than the original, and if you are going new, then why not get even better than original and have more tubes and fins? Many aftermarket radiators have fewer tubes and fins than the original, so even with a new radiator the engine may not run as cool as with the old one. I agree 100% with Milton that you should have your original rebuilt by a reputable shop. You will have the original Harrison end tanks so it will look factory, and you can get a high efficiency core with more tubes and fins than the original. And as Fred pointed out, the trans cooler should be replaced as well. Yes, this is a replaceable item during a rebuild - I had mine replaced when the high efficiency core was installed. I think it was about $15-$20 extra for the new trans cooler, which had more surface area than the original. You see, rebuilding the radiator gives you increased cooling capacity all around.
